Part of me understands having a camera for AR lookups and such, and in my line of work a hands free camera would be amazing especially if I could pull the image back up on the glasses and zoom in on serial numbers etc, but I don’t trust Meta with being on my phone let alone having a live video feed from my eye line at all times.

Other countries use less flammable materials in their construction. Wood frame construction is very common in the US due to drastically lower cost of wood vs block. We also had something called balloon frame construction for many years which made it much more likely for fire to travel within the walls. That being said not having detectors isn’t a great idea either since most are combo smoke and carbon monoxide detectors.
