From what I know, AI is used heavily in China's supply chain management and logistics. This sector being so critical, you can imagine the amount of testing that occurred before being integrated to a level where it began to produce a positive return on investment. Capitalists don't care to invest in this testing themselves and pass that duty onto the consumer. This is why in the west, instead of AI solving real problems, we get the automated slop producing factories that pump massive amounts of CO2 into the atmosphere.
