Would you explain farther how China winning the AI race would result in world war 3 deaths?

Sure, China will build a lead in robotics, drones and weapon tech.

They will invade Taiwan, US defends, WW3.

If they don't have a military/tech lead, the status quo remains.

How does one "win the AI race?"

If there is a concrete finish line, there are likely no winners.

Mura Murati was CTO but not the AI lead. Her role was mostly organizational not scientific.

That's reaching speculation, and a hell of a hypothetical to base your entire argument on.

The "edge AI labs" are both begging for more regulation and a stronger federal presence in their development. Their desire is to be embedded in the killing machine where the monopoly on violence applies, and then abdicate themselves in civil suits when they're held accountable for ethical dilemmas. To get away with it, they have to limit the average Joe and upsell the government the full product.
