I am not going to watch your youtube video.
If you want a proper discussion, mention your points.
Of the 12 problems there are 2 especially bad:
1st (and 2nd) point states that "almost everything depends on programmers". We must trust them! .. And what if they went rogue - someone threaten them (mafia, governmet, ...) or they lose their head - they can introduce all kind of problems - 1.1 exploits 1.2 different exe than given open source ...
No, you don't have to trust them. You can check the code yourself. Everything is open source.
Further, you don't have to take any .exe, you can 1) verify that each release is signed by the developer and 2) if you don't trust the developer (because of mafia or whatever), compile from source. No trust required.
3rd states that there were cases in which big pools had >50% compute power .. I do not think that we have any protection against that right now? Or not?
Protection from what?
From them double spending a transaction resulting in bitcoin getting worthless resulting in them losing their whole business model and making all their mining hardware worthless?
There are easier ways to commit financial suicide than that.
