We all see and hear what goes on over there.
Do we? We only get a little bit of news from there, and I wouldn’t be sure how reliable it is.
Why don’t any other countries step in to help those people.
Help how? Go to war and slaughter most of their population? They are already heavily mobilized, and no doubt they’d conscript a lot more in case of a conflict. Not to mention they have nukes.
Why do we just allow this to happen in modern civilization?
Who is ‘we’? No offence, but this sounds like some oblivious American patriot asking why America hasn’t saved the world yet.
Is just not lucrative to step in?
Most countries don’t have their own nukes, so they will never even consider getting into a conflict with a country that does have them. Most countries don’t have even a fraction of the resources needed for any sort of operation.
Plus, North Korea has powerful allies (like China) and is technically a member of the UN, so you can’t just disregard everything and conquer it.
It’s difficult to prove anything like that. From independent research we know that Intel, and likely AMD too with their counterpart, can remotely control your PC via IME. But they’ve never done that yet or have done so very secretly, because then a lot more people would know and that would be problematic.
Personally I think it’s reasonable to suspect that Microsoft has full capability to severely cripple your system at any given time. Maybe not ‘brick’ as that may be impossible without proprietary hardware inside the machine. However, even a simple Windows installation can mess up your UEFI. Given that, do you think that all those millions of fully secret lines of code cannot render you unable to use your PC, even if just temporarily?
