I can't speak for the others but Two Minute Papers' general format oozes hype. I realize that he tends to recap on exciting topics, but he also sometimes "falls for" research that won't actually pan out for practical reasons. He also tends to cover things in an intensely over-optimistic way ("WOW! WHAT A TIME TO BE ALIVE" on literally every video...) that would have you think every single subject is an absolute major breakthrough when the reality is that many of them simply produced cool-looking demos that look good in a youtube thumbnail.

Sorry if that's too harsh. The channel isn't all bad. The title of the channel is up front about being a quick synopsis that you can watch from time to time to keep up with the latest updates. That's still useful for many people. But it probably won't work as a good _filter_ for what will and will not be quickly forgotten.

In fairness (again), that's a _very_ difficult challenge to solve. It is however the premise of the Ask HN.
