Tesla stock has been riding on the self driving robo-taxies meme for a decade now ? How many Teslas are earning passive income while the owner is at work ?
Cherrypicking the stuff that worked in retrospect is stupid, plenty of people swore in the inevitability of some tech with billions in investment, and industry bubbles that look mistimed in hindsight.
With the smartphone in 2009, the web in the late 90s or LLMs now, there's no element of "trust me, bro" needed. You can try them yourself and see how useful they are. You didn't need to be a tech visionary to predict the future when you're buying stuff from Amazon in the 90s, or using YouTube or Uber on your phone in 2009, or using Claude Code today. I'm certainly no visionary, but both the web and the smartphone felt different from everything else at the time, and AI feels like that now.
