Cool!
I agree! And the investigation was documented in a way that didn’t just tick me off, so that’s a plus. VERY good presentation.
A lot of things I try watching spend the first two minutes with some kind of intro, then remind me of all the things that are either in or suggested by the title, then remind me again, then I leave it and go back to the menu to find something else.
If the reminder to subscribe happens in the first two or three minutes, I dump the vid.
I’d guess than 90% of the documentaries and especially tech vids on YouTube could wrap up the entire presentation in under three minutes. And SHOULD.
