On the one hand, Trump and his idiotic fixation "America First!" goes against all sorts of (unbiased) economic wisdom. I'm strongly against protectionist policies.
But on the flip side, I work in this industry, and China is well known for blatantly stealing American IP. If they won't play by international IP rules, something like this feels like the right response ... I just question if it's really, long-term the right approach, or just a knee-jerk reaction that won't help (and may hurt).
IMO, we shouldn't be banning unless there are real, verifiable security concerns.
Instead, we should be using a combination of tariffs on Chinese robotics, subsidies and R&D investment at home, partnerships with emerging robotic makers like Vietnam, or partnerships with Mexico where there's a robust and growing deployment and software development industry for robotics and automation.
We cannot be an isolated autarky, so we need to treat this as an onion: Strengthen our position at home first, collaborate with markets we are already integrated (Mexico), partner with existing markets (Germany, Japan) or emerging ones (Vietnam) where IP laws are respected, and then seek protections against competitors with unfair advantages or that violate IP laws.
And all of that while luring talent from abroad while cultivating talent at home.
A ban by itself doesn't do anything to prevent competitive stagnation.
