Wikipedia in Video Form is a great line! I feel much the same way, but I think that's not the entire picture. Wikipedia is a lot of declarative knowledge (i.e. what things are and Al's maybe why they are), but YouTube is a lot of procedural knowledge for me. That is how to X. My GF and I finally found an apartment. I don't know how to replace broken light switches, but in five minutes YouTube taught me how.
I didn't know how to replace a faucet - now I do. I did not know how to insert a metal screw fitting into the furniture I was constructing - now I do. I wanted to measure our energy consumption, figuring there had to be a way to it it smart/connected and Open Source. YT content creators showed me how.
