>It seems like the purpose of humans isn't to keep machines busy. When our phone or laptop is idle, it's fine if it sleeps. And when we do want something, we'd rather not wait.

I'm not sure what the original commenter had in mind, but just because our machines are idle when we aren't using them doesn't mean that, that's how we will use computers in the future.

I think notifications are an example even now of the computer not really being idle when we aren't interacting with it.
