I have been hearing (reading?) this for a solid two years now, and LLMs were not invented two years ago: they are ostensibly the same tech as they were back in 2017, with larger training pools and some optimizations along the way. How many more hundreds of billions of dollars is reasonable to throw at a technology that has never once exceeded the lofty heights of "fine"?
At this point this genuinely feels like silicon valley's fever dream. Just lighting dumptrucks full of money on fire in the hope that it does something better than it did the previous like 7 or 8 times you did it.
And normally I wouldn't give a shit, money is made up and even then it ain't MY money, burn it on whatever you want. But we're also offsetting any gains towards green energy standing up these stupid datacenters everywhere to power this shit, not to mention the water requirements.
