They simply aren't reliable in the kind of situations where you're likely to need a firearm though. As I said in another comment, I would want a smart gun to be at least as reliable as a 1911, and--to be very clear--a 1911 is not what I would call a reliable firearm.
I have constant problems with the fingerprint scanner on my phone. If my hands are too dry, no dice. Even slightly wet, nope. Bad day? Yeah, I'm going to have to enter my passphrase. And what if I need to shoot off-hand? Facial recognition? Cameras have a hard time with black and Asian people already, but now my life might depend on a camera getting it right the first time? And might depend on it in bad lighting?
This isn't something I would ever seriously consider.
IMO, if you want-or need--to keep a loaded gun near you while you sleep, just leave it unlocked, and then either lock it in a real security container, or keep it on your person when you aren't in your bedroom.
BTW - I generally avoid anything with Ian McCollum, since he's been pretty clear that he doesn't support 2A rights for everyone (e.g., the poors, LGBTQ+ people, non-white people, etc.), and has generally been acting like a right-wing grifter. Which is unfortunate.
