A Hacker's Mind

It’s not just computers—hacking is everywhere. Legendary cybersecurity expert and New York Times best-selling author Bruce Schneier reveals how using a hacker’s mindset can change how you think about your life and the world. A hack is any means of subverting a system’s rules in unintended ways. The tax code isn’t computer code, but a series of complex formulas. It has vulnerabilities; we call them “loopholes.” We call exploits “tax avoidance strategies.” And there is an entire industry of “black hat” hackers intent on finding exploitable loopholes in the tax code. We call them accountants and tax attorneys. In A Hacker’s Mind, Bruce Schneier takes hacking out of the world of computing and uses it to analyze the systems that underpin our society: from tax laws to financial markets to democracy. He reveals an array of powerful actors whose hacks bend our economic, political, and legal systems to their advantage, at the expense of everyone else. Once you learn how to notice hacks, you’ll start seeing them everywhere—and you’ll never look at the world the same way again. Almost all systems have loopholes, and this is by design. Because if you can take advantage of them, the rules no longer apply to you. Unchecked, these hacks threaten to upend our financial markets, weaken our democracy, and even affect the way we think. And when artificial intelligence starts thinking like a hacker—at inhuman speed and scale—the results could be catastrophic.

I think it's actually appropriate here, and I'll try to articulate why. (Disclaimer: former history major here. I might be biased by my own interests.)

I'm reading "A Hacker's Mind" by Schneier and it makes a fundamental connection I've been trying to reason about for a long time. He looks at hacking through a very broad lens. He defines it essentially as the manipulation of a system using its rules to take actions that are allowed by the system but undermine its intent.

The key thing he says is that systems exist within and connected to broader systems. He gives the example of an ATM. Fundamentally it's a computer connected to a box of cash. You can hack it by manipulating computer rules. But it also exists within the broader monetary and legal systems, and while the computer's rules might allow you to execute the hack, the legal system will always treat that as an illegal action and prosecute you.

So what I'm basically saying is that as a matter of systems thinking, politics makes sense here on Hacker News. I think where people might object is that it can devolve into arguments about values and black-and-white thinking (arguably this essay does that, although I think the Burroughs quote about the bull in the ring approaches a systems theory aspect). Personally I enjoy thinking about this stuff though. Macro-level socioeconomic systems are the largest things we can think about aside from planetary-level concerns like geology and universe-scale stuff like cosmology. Their dynamics are very interesting and interact in many ways with the stuff we think of as more traditionally "hacking."

I was reading The Hacker's Mind by Bruce Schneier and he relays an experiment where a clearly imperfect navigation robot gives wrong directions to people repeatedly. Then a simulated emergency occurs, and the robot changes to saying "follow me to the exit" basically and points to a dark room instead of the routes the people took just minutes before, and despite having experienced the robot doesn't navigate well, people tend to follow the robot's instructions.
