Is the hard evidence of AI being a net improvement for society in the room with us now?

I am unsure what you mean by hard evidence in the context of AI then, what is the evidence we are negating in your view?

We could have had this same argument about social media 15 years ago before hard evidence showed it's not quite the net benefit to society it was touted as.

What is the hard evidence that you speak of?

Are you really comparing LLMs to vaccines? Jesus

You presume there is hard evidence that AI is good for society. In reality, the inverse is true.

Now you understand why anti-vaxxers ignore evidence. Because it doesn't fit with your worldview and you're too narrow-minded and selfish to consider that your viewpoint might actually be wrong and bad for others.
