Comment on Rethinking the Origins of the Lockparent

Comments

is the lock the first machine to do a discrete, conditional action?

Interesting question.

I would guess that the answer is "no". Animal traps based on some kind of triggered action probably predated the keyed lock.

Good point! I feel embarrassed. Thanks.

(Maybe the lock could still get credit for the logical AND?)

Never feel embarrassed for asking a great question!

Agreed.
