The idea is robots aren't racist, which is theoretically true.

I think this is wrong. Robots do pattern recognition better than people do (or at least, they will be able to eventually), and they are less susceptible to anti-racist propaganda, which means an unbiased robot will be way more "racist" than any human.

There are numerous people in the AI industry looking at ways to intentionally bias data sets and algorithms so that robots will intentionally treat people differently based on the color of their skin, in a way that is not reflective of underlying probabilities.

Any robots built by leftists will be anti-racist, which mean they will be hard-coded to discriminate against white people. Putting on a black face mask might actually prevent you from being arrested.

5G control grids

I find 5G very concerning but most of the hype around it seems to be about the specific technology and not the general trend towards higher data rates. Basically I'm concerned about technology in general, but the specific technology in 5G I think doesn't matter. I'll look into how it works but I imagine it's just protocols for data encoding and transfer, microwave frequency bands and so on. Nothing nefarious. It's what can be done with the higher data rate that's the concerning thing.
