Food calories are cheaper to convert into something useful. It's not like GPUs, once bought for peanuts, turn into perpetual motion machines. They need power, cooling, a whole infrastructure built around them.
GPUs would have taken the world by storm already in the roughly 30 years since they've been around.
Even for GenAI it's likely ASICs take over at some point if we really care about performance.
GPUs used to cost 20% of what they cost know and Intel and AMD make perfectly serviceable GPUs for most PCs. NVIDIA top of the line GPUs won't suddenly be plugged in to lowly laptops.
Yes, lots of companies will buy them for cheap, but these AI beasts also have OpEx costs. Not every alternative use is worth the money and there are 0 guarantees that the alternative costs cover the gap. NVIDIA sell 80% of GPUs for AI now.
I think people don't realize just how big this bubble is.
