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.
As much as I don't like it, this is the actual difference. LLMs are already good enough to be a very useful and widely spread technology. They can become even better, but even if they don't there are plenty of use cases for them.
VR/AR, AI in the 80s and Tesla at the beginning were technology that someone believe could become widespread, but still weren't at all.
That's a big difference
With all the insane exposure and downloads how many people cant even be convinced to pay 20$/month for it ? The value proposition to most people is that low. So you are basically betting on LLMs making a leap in performance to pay for the investments.
