Best I can make of some of the "I've been on 5g for months and haven't burst into flame" thinking is...you're thinking of 5g as a singular frequency. Some of the 5g has been in place but 5g as a whole has not.
The frequencies that have been in use are still close to those of common 4g lte but with the introduction of C band 5g it becomes much more powerful and harmful. Its been capped so to speak and now the floodgates are about to open and let loose the whole river instead of a drip from the tap. Also someone send Trin some real cream for his coffee.
