I miss Youtube before #Youtubers became a thing. All sorts of terrific lectures and presentations and so much good and worthwhile material - all just a search away.
And now there's people who's thing is being "content creators" and having "channel followers" and they really do say "like and subscribe".
Great lectures and presentations when I was learning #Python and #Theano in 2016, when learning #Pytorch a few years later. Now I'm learning #Rust, and #Youtube is full of so much garbage.
