Could this technology be used to identify potential threats? Like someone trying to enter a building with weapons? How for could we push this technology? Would it help if there was a merge with Elon musk?

I am guessing that you are asking about facial recognition programs. How do you think that this would prevent someone from entering a building with a firearm? How does someone prevent someone else from entering a building just by identifying that person?

Biometric systems are already used to secure many locations. However, fingerprint, iris and retina scanning are more secure than facial ID. Retrofitting buildings with biometric security systems is bound to be expensive. And, as kb1951 points out, they don't check for weapons. For that, you need metal detectors. Many school shootings (and workplace shootings) have been carried out by people who legitimate access to the buildings.

Elon Musk makes vehicles and batteries. I'm not sure what he would have to do with this.
