I miss the times when there was a lot of technical content that took time and mental energy to understand.

Nowadays, it's pretty hard to discover it. On HN, I see that a lot of technical articles don't make it to the front page, so sometimes I just search for them in the submissions. Not only is there less content, but demand for it is also declining. I guess people would rather read another article about LLMs that teaches almost nothing and doesn't exercise their curiosity. It feels sad for me, as a reader and as a writer.

So, are there any other places left where people still care about and share deep technical content? I want to keep exercising my thinking. I've had enough of brain-rotting.
