If you’re actually curious about the topic, this is an even-handed (reasonably well-informed) take on the matter from physicist Sabine Hossenfelder: ▶ this video One of the interesting points in the video is that 5G’s high frequency band of 24-48GHz is _not_ well understood with studies. The typical cell phone radiation/cancer studies deal with the much lower-frequency bands (hundreds of MHz or 1-5GHz), but that doesn’t necessarily transfer to the new higher frequencies. Per the video, it is known that frequencies that high can warm the skin and irritate the eyes if they’re at really high power, but it’s not known exactly what power threshold for such millimeter waves is considered “safe”, and the number of studies isn’t sufficient to completely dismiss any safety concerns. She’s not saying “5G isn’t safe”, but rather “5G hasn’t been completely determined safe yet because more studies are needed for the newer mm-wave spectrum” and “studies showing the safety of previous generations of cell phone radiation don’t necessarily apply to the new frequency band.” It’s not necessarily alarm-worthy, but it’s more nuanced than just “crystal-worshipping hippies”…
