Fingers crossed for convergence rather than divergence in the technical standards.Although the way hings are going it looks like the 2 stacks will diverge sooner rather than later , with the US+ banning the use of CHN models while simultaneosly banning the export of it quasi-open models.
We may very well end up in a situation like the old PAL vs NTSC video standard where the PAL(EU/Asia/AFrica) and NTSC(America's/Japan) gradually converged with the adoption of digital formats. Instead here would be a divergence based on geopolitical considerations.
positive take: a bifurcated tech tree might give us (humanity) a better chance of faster advancement, as it would be a persistent A/B test in live environment. Where I would join you in the crossing of fingers is to ensure such A/B testing is competitive but not destructive. We may even evolve to a situation of complementarity, an American Ying vs the Chinese Yang. Lets hope so!
