It depends on what we are talking about in regards to "big tech".

It's not clear to me that products like Facebook that are primarily driven by cultural rather than technical dominance are something that the Chinese are likely to be able to dominate in. Facebook dominates because your friends and family and hobbies and whatever are on there, doing their thing. When they stop doing that, Facebook won't dominate anymore.

Now if Han culture becomes internationally dominant as the "cool" culture which North Americans Europeans aspire to emulate (like how American culture was internationally in the post WWII era through, say, the early 90s), then all bets are off -- but I think the trend is actually going opposite to that now.

Until then, there will be social networks that dominate in China and there will be social networks that dominate in Europe and North America; because culturally (and politically, obviously) and they will rarely overlap as these are still two very distinct entities.

I think it's likely that the same argument applies to a lesser degree to the ads space, and maybe even to commerce. Something like AliExpress feels worlds apart from Amazon despite the latter become increasingly a wild west of knock-off discount Chinese products anyways.

Counterpoint: TikTok.

All big movies have random Chinese culture or star included. Han culture may become part of hollywood's core which will spread the culture
