> security through counting on slow hardware

Security through locks doesn't work in the first place. At least not locks that can be picked by this robot. Pick gun is a thing.

Eh, its more that any one security tactic will almost certainly not cover the entire threat space.

Locks are very good at discouraging honest people and lazy, opportunistic people. They are not very good at discouraging generally skilled and motivated people, or people who are specifically interested in what's behind a specific door.

Locks are no obstacle if the intruder is willing to use social engineering. But if all they're trying to do is get into my garden shed, they're going to have to manipulate me or my spouse. Or somehow get past my dog. Meanwhile, my dog has absolutely no bearing on a bad actor getting access to my bank account. But similarly, bringing the full might of the best electronic security to bear to protect a chainsaw and a rake seems a bit excessive. And sort of beside the point, since I've not built my garden shed to withstand creation of an additional door (by e.g. a sawzall or a fireaxe).
