What good has it brought us (not the billionaire owners of AI)? It made us 'more effective' and oh instead of googling something and actually going to a link reading in detail the result we can now not bother with any of that and just believe whatever the LLM outputs (hallucinations be damned).
So I guess that's an upside.
(before the AI god bros come: I am talking purely about LLMs and generative imagery and videos, not ML or AI used for research et al)
