Let me explain exactly why your phone seems to read your thoughts, because the real answer is more invasive than telepathy. Every time you open a website or app, a real-time bidding auction fires in under 100 milliseconds. Your GPS coordinates, browsing history, device fingerprint, age, gender, income bracket, and hundreds of inferred interest categories get packaged into a “bid request” and broadcast to hundreds of companies simultaneously. One company wins the ad slot. All of them keep the data. This happens thousands of times per day per person. A 2018 New York Times investigation found 75 companies pulling precise location data from apps, with some users tracked up to 14,000 times in 24 hours. In 2012, a Target statistician identified 25 products that, purchased in combination, could predict a customer was pregnant and estimate her due date. A teenager’s father discovered she was pregnant because Target sent baby coupons to the house before she told anyone. That was one retailer. Store receipts only. Fourteen years ago. Now scale that. Your phone pings GPS while you sleep. Data brokers link your phone, laptop, and tablet through probabilistic matching of IP addresses, WiFi networks, and behavioral patterns without you ever logging in. The FTC caught two brokers in 2024 categorizing people by visits to reproductive health clinics, political protests, and religious services, then selling those profiles to law enforcement. The algorithm doesn’t hear your thoughts. It compares your behavioral fingerprint against millions of similar profiles and predicts your next interest before you’re consciously aware of it. It makes hundreds of predictions per day. You ignore the misses. The five hits feel like telepathy. You paid for the phone. You pay for the data plan. You generate the signal. And every time a page loads, your identity gets auctioned to the highest bidder before the content even renders. They called it “personalized advertising” because “real-time mass surveillance funded by the people being surveilled” doesn’t fit on a consent banner.

Lost in the Cosmos: The Last Self-Help Book or How you can survive in the Cosmos about which you know more and more while knowing less and less about yourself, this despite 10,000 self-help books, 100,000 psychotherapists, and 100 million fundamentalist Christians or Why is it that of all the billions and billions of strange objects in the Cosmos - novas, quasars, pulsars, black holes - you are beyond doubt the strangest or Why is it possible to learn more in ten minutes about the Crab Nebula in Taurus, which is 6,000 light-years away, than you presently know about yourself, even though you've been stuck with yourself all your life

Is Linux really free, or are we actually paying for it with time, troubleshooting, and stress?

Most people think Richard Feynman was a genius because of his IQ, but an IQ test in high school reportedly placed his score around 125—impressive, but far below what you might expect. What actually set him apart was a habit he developed very early on: metacognitive monitoring of understanding. As a child, his father trained him to notice the difference between knowing a name and understanding the thing itself. When Feynman observed birds, his father taught him that simply learning to label them as birds didn’t matter. What mattered was how they lived, how they behaved, and why. That lesson stayed with him. As a student, Feynman became suspicious whenever an explanation felt simple but left him unable to reconstruct the reasoning himself. Phrases like “it’s obvious” or “it can be shown” were not reassuring to him; instead, they were red flags. Modern cognitive science explains why this matters. Familiarity produces what’s called fluency, and fluency is routinely mistaken for understanding. People feel most confident precisely when their comprehension is actually the thinnest. Feynman learned to treat confidence itself as something to examine. Confusion, for him, wasn’t a failure—it was diagnostic information. A practical way to train this habit yourself is to stop mid-study and ask whether you could explain the idea without using the original terminology. Wherever your explanation breaks down, that’s the true boundary of your understanding.
