lol dude this is flat out wrong. Being able to ask active communitites things is useful to a lot of people. Have you ever even heard of IRC?????
What do you think happened before google had everything indexed?
It's useful to chat it out with people sometimes especially when you are all collectively centered around a single topic.
I've learned mass amounts of things through IRC and often times they don't just give you the answer they give you clues to help you figure it out.
Discord will be similar for many people. It's not necessary to archive every last bit of information. It's OK to talk to real people who enjoy talking about said topic and letting them guide you real time.
