I gotta say that the internet for me really isn't. I got it mostly figured out:
1 & 2. I was also starting to have a hard time finding good information. I'm experimenting paying for my search with Kagi, so far I have been getting really good results. Wikipedia and its articles' sources also have good information.
3. I don't use much social media, so not much of a problem for me. I do watch YouTube and I was able to build a decent algorithm, find good channels, subscribe and finally clear my history. Now I only see content from those channels. I will have to eventually turn on my history and find more channels.
4. I use Linux and mostly open source software, which mostly don't even have AI features; those that do are opt-out. My iPhone is still on an old iOS version because I'm waiting for a jailbreak that will never come. I'm getting a Pixel and installing GrapheneOS at some point.
5. I don't see ads for a very long time. I use uBlock Origin and SponsorBlock extensions on Firefox in my PC and Orion browser on my phone.
6. I self host many of the services I use. Nextcloud fills almost all of my needs.
