It’s because all sites are made by the same “person” now.

If you get past the anthropomorphism, it’s basically that Claude is just a set of knowledge, including opinions (things they’d more likely do than other things) and everyone is getting the same person to make their sites which is why they all look the same.

Also the same reason everything ends up with the same tech stack (if you don’t steer it specifically) which probably contributes to why GitHub is overwhelmed.

Exactly!

I also get the idea that AI writing itself is actually pretty good when looked at in isolation. Try showing it to someone who isn't used to it yet!

It's just that it's a small number of actual "people", and they're ghost writing for millions of folks, from kids to professors.

And because the style is the same, you can't tell which is which from style alone anymore.
