They're garbage when it comes to certain things like helping develop engineering solutions to overcome IC fab ban... at the moment... it would appear. But these things are absolute crown jewels. Each contributes to GDP more than some entire nations. They also developed plenty of innovative tech particularly fintech and software.
I can count on two hands the countries that have equivalent technology conglomerates that contribute so much both in terms of income and technology development. Germany, Japan, S.Korea, USA, China, France, Canada, UK, Sweden. That is literally it I think. Russia's aviation giants are niche and aren't exactly leading their fields anymore. Ukraine ditto. Norway's ship building may lead certain fields but again very niche and nothing like a Sumitomo or Huawei. India's Adani group is a giant and certainly makes money but it isn't in tech really ... not even in the slightest. Not a single thing it is even remotely competitive in let alone close to leading or leading. Energy and construction doesn't count because every country has those... they just aren't necessarily dominated by one guy or family. S.Korea's "equivalent" in Samsung or Hyundai ROTEM does everything from microprocessors to gas turbines to radars to Black Panther tanks... and they lead so many aspects.
9 countries with something like Tencent or Ali who R&D and put into "production"
real consumable products, many that are first in the world and innovative ... again contrary to the cheap internet soundbytes of "China can
only copy and make cheap low tech stuff" lol... China can copy and do it well for sure... but it's got a few more engines gunning at the same time. Other unrisen nations can't even copy when the original guys give them everything and hold their hands through it all
