Fearmongering. Our current understanding of physics precludes 5G from having any effect on the human body. 5G is not ionizing: this is a matter of physical reality. And non-ionizing electromagnetic waves lacks the energy to do anything interesting to matter.

The fear is induced by calling electromagnetic waves "radiation," a scary word. If you accurately called these waves "high spectrum light", the fear would evaporate.

The pedantic scientific caution is that our model of electromagnetism may be wrong. Indeed, light may be small demons seeking to enslave us, and only coincidentally behaving in accordance with the Schrödinger equation, but this is unlikely.

And so it is just as reasonable to outlaw rain dances from subsistence farmers in Africa (Our model of cloud formation could be wrong! Who knows what effect these dances could have?), as it is to be worried about 5G.

Myself, I'm looking forward to high resolution, negligible latency VR, as well as no longer having to buy computer hardware: VM's will perform just as well as your tricked out local computer, so it won't make sense to buy computer (or even a smartphone) anymore. The smarts will live in the cloud, and you'll just need a screen, an input device, and a connection to work or game. 5G is coming, so you might as well be excited about it!
