I mean, you’re not wrong. I’ve been building some unrelated web search tech and have considered just indexing all the sites I can about and making my own “non shit” search engine. Which really isn’t too hard if you want to do say, 10-50 sites. You can fit that on one 4TB nvme drive on a local workstation.
I’m trying to work on monetization for my product now. The “personal Google” idea is really just an accidental byproduct of solving a much harder task. Not sure if people would pay for that alone.
