One thing I was very wrong about: I never thought web browsing on a smartphone would ever become common, as it was and still is such a terrible experience.
I really underestimated how well propaganda works, and how readily people will tolerate ubiquitous surveillance. All that for the promise of fake convenience. Glad I didn’t make any monetary bets on that, as I would’ve lost big.
But it has taught me that how technology works doesn’t actually matter much. Something can be a wholly terrible experience, and with enough propaganda and profit involved, the pigs will line up at the trough of their own accord. Sad to realize, but it has since helped me in the market, so at least some minor good came of it (for me).
