There's been a massive shift in the industry. It's gone from "me and a couple dudes are working on this thing that'll help people live a better life", to "let's lie about what our product can do to reach unicorn status then cash out before anyone notices" and "let's make something that makes people feel dissatisfied with life and keeps them addicted and sells surveillance data to private militaries and governments to threaten our critics."
The good vibes and optimism have left the industry.
It would just be nice if people created good vibes. X is a chaotic mess but there's at least pockets of good vibes. PG still posts over there, as do DHH, Sama, and a bunch of other notable people and people builder things. Here it's been AI, React and political slop for years.
