That is a terrible video....with regards to the exggerations.
I see his point but he has gone WAY WAY WAY extreme in many many points. Like way over, so much exaggerations and there is also a lot of misinformation, or if I put it bluntly, a lot of lies...or BS. I don't think they are going to the dark ages for one thing, or all of the sudden everything they have would stop working and start living in tree houses...dark ages is a bit extreme. China does import energy but this video left out the fact that the reason Japan invaded China in WW2 is it needed resources in China. China has it's own oil and gas resources, also, China can import resources.....do I need to say it??? Russia.
It will be a problem for them for sure but they are not stupid, and the video also ignores that they send a lot of their citizens abroad to study, go to any UK university and you will see lots of Chinese students and then they go back, the skills are there. The reality is that they will be cut off from the very latest cutting edge, 5nm, or 3nm chips, they can still make last gen chips and they do. They will fall behind, like stuck at the current level, for a while, but dark ages is just wrong.
The aging population problem is a different problem, nothing to do with dark ages or silicon chips. That is an economic problem.
ps, they are not really a communist society, that is just a name on paper, in practice, it's more of an autocracy. Communism doesn't mean you can't have good ideas, that isn't what communism is...if that's the case, then they couldn't invent how to type 10,000 chinese characters on a 88 keys keyboard. The US didn't invent that.
I realise this comes across like a China defence but some facts need to be said! This video is very badly researched, very shallow, too much exaggerations to the point that is is actually lies, it left out so much stuff that counters his arguments.
