I can 100% guarantee the current hardware iteration will never support always on recording. It would kill the battery in 45-60 minutes. That added to the fact that almost everyone has a phone on them that can already be geolocated makes using Glass unnecessary for tracking. You could argue that Glass would be useful in taking a photo snapshot every minute but with the growth of security cameras it's estimated that in some areas people are caught on camera as many as 300 times/day. That makes Glass not all that useful.

But it doesn't now, and there is no indication that it ever will aside from people not involved with the product inventing hypotheses. Fair enough if you want to express concern about the trajectory that you envisage, but in your original post you're simply saying it does something that it doesn't.
