None of this is settled, because it's a living system that changes over time. What may have been perfectly true in 1850 might not be remotely accurate in 2050.
The word you're looking for is "collapse". It's when something is stable at one point in time, but then later breaks down. That's what "changed". It wasn't random like weather or something. The economic systems collapsed.

The fact that it has happened numerous times in different parts of the world makes it pretty settled in my mind.
There’s a whole bureaucracy just to coordinate the implementation at the sector, provincial, and corporate level driven by the State Council, NDRC, and NPC. Governments at all levels are involved with coming up with their own implementation plans to execute on the Five Year Plan.
You can trace decades of Chinese industrial development to those plans but the Chinese system is very different from the Soviet central planning mechanism, which is why I think you’re misinterpreting Alibaba’s price competition. The CCP explicitly allows non-state owned enterprises like Alibaba and the manufacturers on it to compete; that’s their whole point within the system, and they operate within the regulatory environment setup to promote the five year plan instead of quotas like the Soviet system. The resolution of the planning is different, but it’s very much there.
Now go look at the 5 year plan from Beijing. Green technology, robotics, mature node chips, and AI are the focuses.
In other words, it isn’t a mistake that China dominates in the industries that it does.
Have you asked people in China about this?
