A button that does nothing
for ten seconds.

That was ten seconds.

Nothing broke. You did not fall behind. The button did not need to respond the instant you touched it.

Most software treats the time between wanting and doing as latency, a delay to be shaved to zero. Sometimes it is latency. Sometimes it is judgment, and the ten seconds were not a wait. They were the decision, handed back to you.

Friction is not always a defect. Sometimes it is the part of the interface that remembers there is a person on the other side. And zero is a design decision too. The instant button is a choice, not the absence of one.
