The thing about Y2K was a problem but it was fixed to an extent. There may have been excessive hype placed on Y2k similar to the hype placed on Covid in 2020, just twenty years later.

I was sorta not aware of these things in this list, in that video, including the thing about the Halloween candy, I imagine it was simply parents using common sense to be careful.
