Sadly quite often these youtubers and others who speak a lot about a lot of different topics with a sort of surface level understanding are very often quite badly wrong. Especially the ones who say stuff like “X is best because its used in Y application”

That level of simplification is not very healthy for most stuff. Of course, there are some channels that do talk about a lot of topics but do very good research and/or ask for experts to help out with their script.
