So is your concern more about reducing the risk of an authoritarian China "winning" the AI race? And less about reducing the risk of your data being used against you personally?

To me, the risks of an individual helping China to continue to develop their AI by being a customer is pretty marginal compared with the personal risks of my data being used against me.

I see. Though if you follow the argument set forth by Dario, it seems you'll not only have your concern to worry about (i.e., personal risks of your data used against you), but many more as well on top of that.
