Search has been steadily headed this direction for a long time, but recently (in just the last couple of months) I’ve started to notice a big uptick in obvious ChatGPT content in places that have otherwise been less egregiously SEO’d: StackOverflow answers, a real person’s personal Medium blog, comment sections on blogs that have good discussions, Github issues, etc.
Unfortunately I have to imagine this is only going to lead to more closed communities and less free sharing of knowledge.
