8 Technology & Society IIa

Technology and Society - Intermediate

Part 1 - Technology and the Human Story

Homo sapiens exists because of technology. About 1.9 million years ago, our ancestors began using fire — and this single technology may have changed the course of human evolution itself. One of the most influential hypotheses in paleoanthropology holds that cooking food made it easier to digest, breaking down tough fibers and proteins that would otherwise require enormous amounts of energy to process. The energy our ancestors saved on digestion became available for something else: larger, more complex brains.

Cooked food is more calorie-dense and easier to extract nutrients from than raw food. This, the hypothesis argues, allowed early humans to support the metabolic demands of bigger brains, which consume roughly 20% of the body’s energy despite being only about 2% of body weight. The exact timeline and mechanism are still actively debated — the archaeological evidence for controlled fire doesn’t fully align with when the evolutionary changes appear in the fossil record — but the core insight is beyond dispute: technology reshapes human biology, not just human capability.

A well-documented example sits much closer to the present. When populations in Northern Europe, East Africa, and Central Asia independently developed dairy farming thousands of years ago, something remarkable followed: the ability to digest milk as an adult — normally switched off after childhood — evolved separately in each of these populations. At least five distinct genetic mutations producing this trait spread rapidly in dairying communities because they conferred a real survival advantage. The same trait evolving independently five times in populations that all developed the same technology is powerful evidence of something profound: we shaped our tools, and our tools shaped us back.

Technology isn’t something that happened to humanity; it’s what made humanity possible. Every significant human capability has been extended, amplified, or enabled by technology:

Language itself is a technology—a system for encoding and transmitting thoughts across space and time
Writing extended language beyond the limits of memory and lifespan
Agriculture allowed population density and specialization that created civilization
Medicine extended lifespan and reduced suffering across billions of people
Tools and machines multiplied the physical capabilities of human bodies
Communication networks connected minds across continents in real-time

This isn’t a recent development. Humans have been inseparable from our technologies for millions of years. What’s changed is the pace of technological change and the complexity of dependencies we’ve created.

Understanding technology isn’t optional knowledge for specialists—it’s fundamental to understanding what humans are, how society functions, and how to participate meaningfully in shaping our collective future.

Our Deep Dependencies: Technology as Infrastructure

Most people dramatically underestimate how dependent modern society is on technology. It’s not just that we use smartphones and computers—it’s that nearly every aspect of contemporary life depends on complex technological systems that most people never see or think about.

Food systems: The food in your home traveled through a technological chain: industrial agriculture (tractors, irrigation, fertilizers, pesticides), processing facilities, refrigerated transport, supply chain management software, point-of-sale systems, and home refrigeration. Without technology, most cities would face starvation within days. Urban population density is only possible because of agricultural and distribution technology.

Water and sanitation: Clean water doesn’t come from nature in most places—it comes from treatment plants, pumping stations, filtration systems, and distribution networks. Sewage doesn’t disappear—it’s processed through wastewater treatment systems. These technologies prevent the waterborne diseases that killed millions throughout history and still kill hundreds of thousands annually where these systems don’t exist.

Electricity: Modern life assumes constant electrical power. Hospitals depend on it for life-support equipment. Food storage depends on refrigeration. Communication systems require power. Banking, commerce, and government services all run on electrical infrastructure. A sustained power grid failure would cascade into failures across every other system.

Medicine: Antibiotics, vaccines, insulin, chemotherapy, surgical techniques, diagnostic imaging, anesthesia—modern medicine is entirely technological. Life expectancy has roughly doubled in the past century primarily because of medical technology. Conditions that were death sentences a generation ago are now manageable chronic conditions.

Communication: The internet isn’t a single technology—it’s an interconnected system of fiber optic cables, satellites, cell towers, routers, protocols, and data centers spanning the entire planet. This infrastructure enables not just entertainment and social media, but emergency services, financial systems, supply chains, research collaboration, education, and democratic participation.

Transportation: Personal vehicles, public transit, freight shipping, air travel—all depend on fossil fuels or electrical grids, road/rail/air infrastructure, GPS satellite networks, and complex logistics systems. The global economy depends on the ability to move goods and people reliably. A disruption in shipping technology affects everything from medicine availability to food prices.

Finance: Money itself has become primarily technological—digital ledgers, electronic transfers, credit cards, stock markets, cryptocurrency. The physical cash in circulation represents only a tiny fraction of the money supply. Banking, investment, wages, purchases—all flow through technological systems.

Why this matters: These dependencies aren’t inherently bad, but they create vulnerabilities that most people don’t recognize:

Cascading failures: When one system fails, it can trigger failures in dependent systems. A cyberattack on a power grid can disable water treatment, disrupt hospitals, halt transportation, and collapse communication.
Invisible fragility: Systems that work reliably for years can fail catastrophically with little warning. The more complex and interconnected, the harder to predict failure modes.
Loss of traditional knowledge: As technology replaces older methods, knowledge of alternatives disappears. Few people today know how to grow their own food, preserve food without refrigeration, navigate without GPS, or treat illness without modern medicine.
Centralization of power: Control over critical technological infrastructure means control over society. Those who operate, regulate, or can disrupt these systems hold enormous power.

This isn’t an argument against technology or for primitivism. These systems have created unprecedented prosperity, health, and capability. But informed citizenship requires understanding what these dependencies are, how they work, and what happens when they fail. You can’t make good decisions about infrastructure investment, technology policy, emergency preparedness, or climate adaptation if you don’t understand how deeply society depends on technological systems.

As you’ll see in Level 3: Systems Thinking, these technological dependencies create complex feedback loops, emergent behaviors, and system-level risks that aren’t obvious from looking at individual technologies in isolation.

Understanding and Navigating Dependencies

Recognizing these dependencies isn’t about becoming a survivalist or rejecting modern technology—it’s about informed participation and reasonable resilience. Here’s how to make this knowledge practical:

Learn how your local systems work:

You don’t need to become an engineer, but understanding the basics of critical systems in your community helps you:

Vote intelligently on infrastructure issues: When there’s a ballot measure about water treatment upgrades or electrical grid improvements, you can evaluate the actual need rather than relying on political rhetoric
Recognize real vs. manufactured crises: Is that “emergency” infrastructure project genuinely urgent, or is someone exploiting fear for profit or political gain?
Participate in planning: Many communities have public meetings about infrastructure, zoning, and technology policy. Informed residents can advocate for better decisions.

Where to start learning:

Your local utility companies often offer tours or educational materials about water treatment, power generation, waste management
City/county planning departments publish infrastructure reports and maintenance schedules (usually online)
Local emergency management offices provide information about critical systems and vulnerabilities
Community colleges often offer courses on utilities, building systems, and infrastructure
Documentaries and books on specific systems (see sources at end of this section)

Build reasonable personal resilience:

Understanding dependencies helps you prepare sensibly without paranoia:

Basic emergency supplies: Water, non-perishable food, flashlights, battery-powered radio, first aid kit, necessary medications. This is standard emergency preparedness, not extreme prepping.
Backup capabilities: Know how to do critical tasks without your primary technology. Can you navigate without GPS? Cook without electricity? Access important information if the internet is down?
Community connections: In emergencies, communities with strong social ties (see Level 2: Community & Cooperation) recover faster than isolated individuals. Technology often fails; human cooperation rarely does.
Financial resilience: Keep some cash on hand in case electronic payment systems fail temporarily
Knowledge resilience: Learn basic skills that don’t depend on infrastructure—cooking from scratch, basic first aid, bicycle repair, etc.

Critical thinking about new dependencies:

When society adopts new technologies that create new dependencies, ask:

What happens if this fails? Are there backup systems? Manual overrides? Alternative methods?
Who controls this system? Is it publicly owned, privately owned, or mixed? What are the incentives and accountability mechanisms?
How resilient is it? Can it withstand natural disasters, cyberattacks, supply chain disruptions, or other shocks?
Who benefits and who’s vulnerable? Do the benefits and risks distribute fairly across the community?

Case study: The 2021 Texas power crisis

In February 2021, a severe winter storm overwhelmed Texas’s electrical grid, leaving millions without power for days in freezing temperatures. At least 246 people died. This illustrates multiple dependency lessons:

Cascading failures: Power loss disabled water treatment plants, causing water shortages. Natural gas production (which requires electricity) dropped, reducing power generation further—a negative feedback loop.
Infrastructure assumptions: Texas’s grid was designed for summer heat, not extended freezing. Climate change is creating conditions outside historical parameters.
Market structure matters: Texas’s deregulated, isolated grid prioritized low costs over resilience. The technology existed to winterize systems—economic and political decisions prevented it.
Inequality of impact: Wealthier residents could leave or had backup generators. Poor residents in inadequate housing suffered disproportionately.
Community response: Neighbors shared resources, opened homes, checked on vulnerable people. Technology failed; human cooperation filled gaps.

Lessons applicable everywhere:

Infrastructure isn’t just technical—it’s political and economic
Climate change challenges assumptions built into existing systems
Backup plans and redundancy cost money upfront but save lives during failures
Understanding your dependencies before crisis hits enables better preparation
Community ties matter as much as individual preparation

Case study: COVID-19 and supply chain visibility

The pandemic revealed how little most people understood about supply chains:

Global interdependence: A chip shortage in Taiwan affected car production worldwide. PPE manufacturing concentrated in China created shortages everywhere else.
Just-in-time fragility: Efficient supply chains with minimal inventory collapsed when demand spiked or production paused
Technology enabled adaptation: Remote work, telemedicine, online education became widespread because infrastructure existed. But this also revealed the digital divide—those without reliable internet access lost educational and economic opportunities.

Practical outcome: Many people now understand that “where does this come from?” and “what if that source is disrupted?” are important questions about critical goods.

Becoming informed about specific systems:

You can’t understand everything, but you can develop literacy in systems that matter most to you:

If you care about food security: Learn about agricultural technology, food preservation, local vs. global supply chains, refrigeration infrastructure If you care about health: Learn about pharmaceutical supply chains, medical device technology, hospital systems, telemedicine capabilities If you care about climate: Learn about energy systems, grid technology, renewable vs. fossil infrastructure, transportation systems If you care about privacy/freedom: Learn about communication infrastructure, surveillance technology, data systems (covered extensively elsewhere in this topic)

Resources for deeper learning:

How Infrastructure Works by Deb Chachra (2023)—accessible overview of systems thinking applied to infrastructure
YouTube channels like Practical Engineering—technical explanations made accessible
Your local utility websites and public reports
Trade publications in specific fields (often free online)

The goal isn’t to become an expert in everything—it’s to develop enough understanding that you can:

Ask informed questions
Recognize when you’re being misled
Evaluate trade-offs in technology and infrastructure decisions
Participate meaningfully in democratic decisions about technology
Prepare reasonably for likely disruptions
Understand how your individual choices connect to larger systems (explored in Level 3: Systems Thinking)

How It Connects — Section 1: Technology and the Human Story

This section sits at the intersection of history, systems, and personal resilience, which makes it one of the more broadly connected topics in the program. Here’s how it links to the rest of Techne:

Level 1: External Barriers Technology is one of the most powerful forces shaping external barriers — it can remove them (clean water, medicine, communication) and create new ones (infrastructure dependence, unequal access, cascading failures). This section gives concrete depth to the abstract concept introduced in Level 1.

Level 1: What Are People Capable Of? The story of fire, cooking, and brain evolution is a direct example of human potential being expanded through technology. Every tool humanity has developed is an extension of what people are capable of — this section illustrates that principle across history.

Level 2: Critical Thinking Understanding which technologies are reliable, which dependencies are risky, and how to evaluate infrastructure claims all require the habit of asking evidence-based questions. Critical thinking is the tool you use to assess the systems this section describes — without it, it’s easy to take fragile dependencies for granted or accept reassurances uncritically.

Level 2: Science (as a process) Many of our deepest technological dependencies (medicine, food systems, water treatment) are the direct products of scientific knowledge. The scientific process is also the best tool we have for identifying weaknesses in those systems before they fail.

Level 2: Education (as a concept) Building personal resilience — one of this section’s practical recommendations — requires knowing how to learn new skills quickly and seek out reliable information. Education as a lifelong practice is what makes adapting to changing technological realities possible.

Level 2: Long-term Thinking The invisible fragility of modern infrastructure is essentially a long-term thinking problem. The risks of deep dependency are slow-building and often invisible until a crisis reveals them. Long-term thinking provides the mental habits for anticipating these risks before they become emergencies.

Level 2: Community & Cooperation No individual can personally maintain resilience across every system they depend on — that’s not realistic or even desirable. Community resilience is more robust than individual resilience. Knowing your neighbors, building local networks, and contributing to community preparedness are all cooperation principles applied to the realities this section describes.

Level 3: Systems Thinking Cascading failures — where one disruption triggers others across connected systems — are one of this section’s central warnings. Systems Thinking provides the formal conceptual tools (feedback loops, interdependencies, tipping points) for understanding why cascading failures happen and how to anticipate them. This section is an applied preview of those concepts.

Level 3: Part-Whole Symbiosis Personal resilience (understanding your dependencies, building redundancy) strengthens community resilience; community resilience reduces the burden on individuals. This is a direct expression of the Part-Whole Symbiosis principle — each part making the whole more robust, and the whole reducing vulnerability for each part.

Level 3: Systemic/Institutional Change The fragility exposed by events like the 2021 Texas power crisis isn’t just a personal problem — it reflects policy choices, regulatory failures, and institutional decisions. Addressing it at scale requires exactly the kind of systemic and institutional change that Level 3 explores.

Advanced Practice Exercises — Section 1: Technology and the Human Story

Comprehension Check

The section argues that technology is “the defining characteristic of humanity.” In your own words, explain the chain of evidence connecting fire, cooking, and brain evolution that supports this claim. What makes this example more significant than simply saying “humans use tools”?
What is a cascading failure? Describe the general mechanism — how does a disruption in one system spread to others — and use one of the case studies from this section (Texas 2021 or COVID-19 supply chains) to illustrate it.
The section distinguishes between technologies we use and technologies we depend on. What is the difference, and why does it matter for how we think about risk?
What does “invisible fragility” mean in the context of modern infrastructure? Why is fragility more visible during a crisis than during normal operation?

Reflection Exercises

Think about the last 48 hours of your life. Pick three things you did or consumed — a meal, a communication, a trip somewhere, a medical product — and trace each one back through the systems that made it possible. How far back can you get? Where does the chain become unclear to you?
The section describes a gradual accumulation of dependencies over generations, most of which we never consciously chose. Do you feel that deep dependency on complex systems is mostly a good thing, mostly a risk, or something more complicated? What shapes your answer?
Have you ever personally experienced a significant infrastructure disruption — a power outage, water advisory, supply shortage, or similar event? If so, what did it reveal about your assumptions? If not, what do you think that experience would reveal?
Building personal resilience — learning skills, understanding local systems, maintaining some reserves — takes time, energy, and sometimes money. Given your actual life circumstances, what level of resilience-building feels realistic and worthwhile to you? What gets in the way?

Application Exercises

Dependency audit: Choose one critical system in your life (food supply, water, electricity, internet, or medication). Research how that system actually works in your specific location — where it comes from, what infrastructure it relies on, what the known vulnerabilities are, and what backup systems (if any) exist. Write a brief summary of what you found and what surprised you.
Resilience inventory: Make an honest assessment of your current personal resilience for a 72-hour disruption to one essential system. What do you already have in place? What gaps exist? Identify one concrete, achievable step you could take in the next month to reduce a specific vulnerability.
Local systems map: Sketch (on paper or digitally) a simplified map of the key infrastructure systems your household depends on — energy, water, food, communication, transportation, healthcare. Draw connections between them where they share dependencies. Where do you see single points of failure or dangerous overlaps?
News analysis: Find a recent news story (within the last year or two) about an infrastructure failure, supply chain disruption, or technology outage anywhere in the world. Apply the cascading failure framework from this section: What was the initial disruption? What secondary and tertiary effects followed? What dependencies did it expose?

Discussion Exercises

(Partner or group) Share your dependency audits from the Application Exercises. Did you research the same system or different ones? What did each person discover that others hadn’t considered? What does it feel like to map out how little you personally control about the systems you depend on?
(Partner or group) The section notes that modern infrastructure has dramatically improved human wellbeing — longer lives, less disease, less starvation — while also creating new fragilities. As a group, try to define what a genuinely good relationship with technological dependency would look like. How much dependency is acceptable? What kinds? Who should be responsible for managing the risks?
(Solo journaling or group) The Texas 2021 power crisis disproportionately harmed low-income and elderly residents. COVID-19 supply chain disruptions hit some communities far harder than others. What does unequal vulnerability to infrastructure failure reveal about how these systems were designed and for whom? What would more equitable resilience look like?
(Partner or group) If your community had to increase its resilience to a specific infrastructure risk — say, extended power outages or food supply disruptions — what would that actually require? Think through the practical, social, and political challenges. Who would need to be involved? What would the biggest obstacles be?

Research & Evidence — Section 1: Technology and the Human Story

Foundational Sources

Richard Wrangham — Catching Fire: How Cooking Made Us Human (2009, Harvard University Press) The primary scientific source for Section 1’s opening argument. Wrangham, a Harvard primatologist, presents the evidence that controlled fire and cooked food drove the evolutionary changes distinguishing Homo sapiens from earlier hominins — smaller gut, larger brain, reduced jaw musculature. Accessible to non-specialists while remaining rigorously grounded in evolutionary biology and anthropology.

Charles Perrow — Normal Accidents: Living with High-Risk Technologies (1984; updated edition 1999, Princeton University Press) The foundational text on cascading failures in complex systems. Perrow coined the term “normal accident” — failures that are predictable, even inevitable, consequences of how tightly-coupled, complex systems are designed, rather than the result of individual error or bad luck. This is the theoretical backbone of Section 1’s discussion of invisible fragility. Essential reading for anyone who wants to understand why modern infrastructure fails the way it does.

Vaclav Smil — Energy and Civilization: A History (2017, MIT Press) Smil is one of the most rigorous analysts of how energy systems underpin all of civilization’s capabilities. This book traces the relationship between energy and human development from fire through fossil fuels and beyond, providing deep quantitative grounding for the dependency claims in this section. Dense but rewarding; his shorter Energy: A Beginner’s Guide (2006, Oneworld) is a more accessible entry point.
