I completely agree with that, but the problem is finding a supply of people to argue with on niche subjects. I have occasionally argued with people on the Haskell IRC and the NixOS Matrix server about some stuff, but since they're humans who selfishly have their own lives to live so I can't argue with them infinitely, and since the topics I argue about are specific there just don't exists a lot of people I can argue with even in the best of times.
ChatGPT (Gemini/Anthropic/etc) have the advantage of never getting sick of arguing with me. I can go back and forth and argue about any weird topic that I want for as long as I want at any time of day and keep learning until I'm bored of it.
Obviously it depends on the person but I really like it.
