Whilst manufacturing has more practical value than much of what's in datacentres[1] it doesn't necessarily follow that it's the more valuable strategic play or route to long term economic growth (bubble or no bubble)
Food is more critical to us than Alibaba crap or even top notch smartphones and would be missed rather more if we had a nuclear exchange, but Chinese entrepreneurs would rather own factories exporting manufactured goods than rice paddies, and for good reason. The Chinese government would like to be self sufficient with food production, but unlike many less technologically developed countries it isn't. Most of those countries stay poor though. Food doesn't change or scale as much as manufacturing, which possibly doesn't change as fast or scale as big as compute. Plus in theory at least, some of the compute is being devoted to automating away dependency on offshore labour for manufacturing, although I suspect China is generally ahead in the manufacturing automation areas of AI anyway...
