From someone who has been in the industry a long time this seems like a fair analysis. The simple fact is it's not necessary to do any sort of long term testing on the human effects of millimeter wave, as up until now there was just no useful purpose for that spectrum for the most part. Anyone giving an absolute answer either way is just lying.

Myself, I'm not super bothered by it. Although I'm way more than happy enough with existing LTE service quality anyway. Those frequencies penetrate damn near nothing at the lower power.

Something else that was sort of touched on, if you are worried about it--then the real risk is your phone anyway, not the tower. Bear in mind that for two-way communication to work the phone has to talk back to the tower and it uses the same frequencies. It's also actually close to your body.

I've read scare tactics with respect to how much power towers draw, but that's mostly processing equipment. Not just the RF gear, there's a lot of computing power. Just think of how crazy a graphics card has gotten compared to 20 years ago. Then think of that translated into some equipment that costs hundreds of times more and is essentially a bunch of specialized CPUs that turn electricity into heat. There is a ton of this type stuff that supports 5G. The actual power the RF interface uses is so small it's negligible.
