I want to point out that they weren't necessarily building a great lock.

The "great product" bit seems to be the usual consumer startup rhetoric by the CEO, which many people fell for.

I can confidently say that it is marketing rhetoric because a similar example already exists in the world: car locks.

I still drive a car where you have to manually insert the key and turn it to open the door.

I've also driven cars where the locks are remote controlled.

I've also seen cars where you press your thumb to the lock to unlock it.

There's nothing "great" about any of the above after the first two or three uses.
