I think any one country becoming the global "superpower" of AI is unsettling.
As utopian as this sounds, the only way AI's evolution can be a positive thing is if we develop it collectively to create a post-scarcity world. It's the fight for resources in a resource-scarce world that fuel such competition in the first place.
Approaching AI from a competitive angle could end in humans being killed off.
Or, it could be this competition that could help bring out some of the best AI technology we've ever seen. These innovations could be life-changing (in a good way) don't you think?
