One area where I'll be worried about China (not sure India as it's following USA in many ways) is they needn't spend time, resources on ensuring political compliance. Maybe yes in a different sense but not in the same sense as in returning "correct" answers for questions. We saw that with Google.
That should knock God knows how many GPU cycles, time and training of models.
I'm not sure it's easier to make your products block communication about Taiwan or Tiananmen Square.
If you have to do political policing one way or the other, you'll have to invest resources to achieve it. On the other hand, maybe it's beneficial for r&d because it pressures you to do hard things that your product benefits from, e.g. controllability in ML-products.
