Hate hate hate AI with the passion of 1000 burning suns.
Used to go to bed by thinking about some moon, planet or other astronomy subject and searching for a good lecture by typing the name of the subject followed by the word 'lecture'.
Usually there were a couple short basic videos, but also experts with hour plus long technical presentations. Those are all gone now. Replaced by absurd AI bullshit slop videos that can't even pronounce technical terms correctly. It's all garbage.
