Those are showing up. The robots *are* coming. But not just to the US.
The US surged to dominance in the aftermath of WWII, when most of the other major countries had sustains severe damage. Since then, they have recovered, so the US no longer has that much advantage. Several of the other countries are smaller, or have other disadvantages, but the US has some disadvantages of its own. And we've essentially abdicated out position. China seems to be moving in to fill the vacancy. (Don't take this too seriously, I don't spend much time analyzing this stuff, but that's my take.)
AI *IS* going to be extremely important and shape the world over the next decade. It's an extremely important thing to get right, and getting it wrong could be deadly. But it's already clear that it's going to dominate repetitive jobs. And China is well aware of this. So, apparently, is Amazon, and a few other places. What's not clear is just how cheap it will be. (But China is pushing it hard...so probably cheaper than humans.)
