I've been wondering if there is any actual innovation behind this round of "AI" hype besides the sheer scale. But the polarisation (in which I'm painted as anti-, bit of a simplification...) made it difficult for me to tell!
3Blue1Brown mentioned that transformer models were innovated in 2017, which is what allows us to throw so much hardware at the problem.
Took 4 or 5 years to bring it to market at said scale, but that seems about right!
1/1.5!
