The author did not say every dollar was wasted, he said that LLMs will never meet the current investment returns.
It’s very frustrating to see comments like this attacking strawmans and setting up Motte and Bailey arguments every time there’s AI criticism. “Oh but LLMs are still useful” and “Even if LLMs can’t achieve AGI we’ll figure out something that will eventually.” Yes but that isn’t what Sam and Andreesen and all these VCs have been saying, and now the entire US economy is a big gamble on a technology that doesn’t deliver what they said it would and because the admin is so cozy with VCs we’re probably all going to suffer for the mistakes of a handful of investors who got blinded by dollar signs in their eyes.
