Large chunks of the internet could easily be replaced with generative AI because people are just repeating, at best, conventional wisdom and at worst the marketing for various products or standards.

So

I spent the last 2 hours working out PSNR values from a reference with various parameters. And the people indistinguishable from generative AI are mostly correct, although they don't know why, or by how much or under what circumstances.

Not that it's that important. It just annoyed me.
