The problem is that we can no longer trust whether something we're reading is an actual thought that someone had, or if it's copy-pasted garbage that's put there for internet points. The extra effort that comes from that decision is what causes the fatigue.
The internet was low-trust before, and now it's zero-trust.
That's the thing though, you say copy pasted garbage based on what? What if its impeccable code, some of the best you've ever read, has zero bugs, but then you find out just before downloading it, that AI was used for it. Do you throw it all away as slop? You don't even know how much was done by AI by this point mind you, what if it was very little, what about half? What if all of it was AI, 100% of it, but you didn't even notice before, so where's the bar? Are we after quality or just "a human must have spent hours for me to use the code" which is it? Because for me it's just is it reasonable quality? Then I'll use it. In fact, I use things I "vibe coded" for myself everyday, rarely finding bugs.
