Sure, but “being dumb” isn’t an exclusive club for people with low intelligence. There plenty of very smart people that are also dumb. Hell, most AIs could be classified as smart but dumb.

I’ve been hearing that the “changed handle” thing isn’t valid, because when an account handle is changed you can still see the original on the user’s profile (and that wasn’t the case for the littlestjeff account).

It’s not an “if” detector, it’s a “how much” detector. It looks like it’s using the LED chamber to light the film in a consistent way, and then the phone camera measures the color change to quantify how much radiation it was exposed to.

One aspect to consider is exactly what data these devices are exfiltrating from your network. You usually can’t see the contents of the telemetry sent, but given that a LOT of smart devices have cameras and/or microphones, do you really trust that your IoT devices are not sending back audio and or video recordings of the inside of your house?
