This is how I feel completely, having also grown up online all the way from BBSs onwards. I literally don't even have websites to visit any more. I get on my computer, scan hacker news for a bit, check twitter for a few minutes, scan some world news site, and thats it.
I still spend a lot of time programming (and thus a lot of time on the computer) but other than that, absolutely nothing appeals. Its a wasteland in my mind.
I have said it for a while, Hacker news is the last place that still feels like the old internet, but even then I'm not a huge fan of it. Some days I open it up to see just 30 stories about LLM's, something I have little to no interest in.
While sites like Neocities are trying to keep the old web ideals alive, even there it can be difficult to find much of value.
