If you claimed that AI was inevitable in the 80s and invested, or claimed people would be inevitably moving to VR 10 years ago - you would be shit out of luck. Zuck is still burning billions on it with nothing to show for it and a bad outlook. Even Apple tried it and hilariously missed the demand estimate. The only potential bailout for this tech is AR, but thats still years away from consumer market and widespread adoption, and probably will have very little to do with shit that is getting built for VR, because its a completely different experience. But I am sure some of the tech/UX will carry over.
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.
