If someone it's interested at reading about the effects of TV and internet into modern culture you should read a book named Homo-videns by Giovanni Sartori.
Beside the book, I believe the boom of ADHD diagnostics could be related to modern technology use and its effects on brain development, psychological and emotional.
I use Docker and it works for what I use it so I have no need to change it, maybe if in the future I have the need to use podman I would consider to change. But right now I'm not interested.
I learned it from trying an error, look for Docker documentation and you can start self hosting something like NextCloud or Jellyfin. Any software which have a Docker image can work for you to learn. You can use "AI" like Bing if you have any doubt too
Someone should make a non-restricted "AI" and let the world burn down. What's the point into censor it?
