Smaller black holes are harder to construct but way more useful.
Black holes are likely the most efficient form of power generation that we currently know of.
Black hole propulsion may well be the best form of interstellar starship propulsion.
Black holes may also be the ultimate computer.
If the universe continues based on it current understanding then eventually all the stars will be dead and the universe will be a dark place. The Black hole era will last trillions of time as long but may well be the golden age of civilization.
Each of these topics is a rabbit hole.
If find it hard to take a presentation like this serious. Most of the mentioned facts are right as far as i can judge it without having a major in physics, but to me this is so very much worse than a link to backreaction (Sabine Hossenfelder), startswithabang (Ethan Siegel) or almost any other serious physics blog out there as anything else.
I suppose this will get downvoted, and I'm fine with that, but please explain to me why a self-promoting video guy with probably 5% understanding of the matter compared to a serious pop-sci blog is so relevant to you.
Heck, even wikipedia has more information than this clip. And it doesn't cost 13 minutes + ads, just 5 minutes to read.
It's not a paradox a neutron star gets smaller the more mass you add to it. This is also true for Jupiter-sized objects; it is a function of density, matter and gravity, and not related (in this case) to special relativity.
You are free to not like his mass-market material, but from a technical level, he is quite qualified to talk about the subject.

Maybe as a default position, you should assume less about someone’s credentials based on hand gestures and haircuts.
