This article doesn't talk so much about "muh five gees turnin on muh covids," although it does briefly try to imply that. It's a very badly written piece about the dangers of giving China the technology, and letting them build it - but considering China is one of the members of the development council, it's hard to see how that's not going to happen.

I agree that China is a clear and present danger, they could simply cut off technology supplies and we'd be fucked. But there are more rational ways to approach that danger than this article.

Your talk about the frequency ranges are spot on, we've had stuff in the L, S, C, X, and K/Ka/Ku bands forever, including satellite broadcast and RADAR systems. While sitting there pointing an X-band radar gun at your leg for 20 years is probably going to give you cancer, it's not going to do shit anywhere else. 1W of 24GHz cellular probably isn't going to work very well in your house.

5G is simply a signaling standard on pre-existing frequencies. "Signaling" simply means the method of modulation. It's like saying the change from greetings of "good day", from, "hello", means we're all going to melt like in Raiders of The Lost Ark. This is precisely how insane the 5G-end-of-the-world people sound to educated people. There exists no scientific nor physics basis for their position. It's simply profound ignorance combined with induced hysteria.
