I'm not 5. I don't need to 'say it with you now.' Take that smug attitude and shove it up your ass.
Physical locks with heavy-set sprung pins, double shear lines, mushroom pins, and additional security features can be almost unbreakable given the amount of effort and noise that picking or breaking them will incur.
Your post is a contrite logical fallacy. The bluetooth mirror is trivial to execute once the mirror is created. No one has to 'follow around', they walk next to you for 2 seconds, and the signal is transferred bidirectionally, the door unlocks.
Yes, it is way less secure than an existing deadbolt. Your post is akin to saying a new operating system is secure because no viruses have been coded for it. And we might as well put shitty locks on our doors, because they can break in through the window anyways..right..and no one has bars on their windows, because you don't?
Now, say it with me: "I'm okay with lax security, so everyone else should be too."
Also say: "I don't know shit about pin-tumbler locks, so I can make posts about security to misinform other people."
Now slap yourself twice for being a dolt.
Thanks, class. Now back to nap time.
