Yeah, at the end of the day, when it's, say, Tuesday 4:00 AM and your eyes start to close harder then you can hold them, you are still looking at some shitty and not interesting at all comments on HN, you are almost asleep. You feel it.

Now your eyes are closed, you think you will asleep right now. You are closing your laptop. You are ready to asleep. And then (!) you start remembering that you need to set an alarm! You go through pain of your eyes trying to set the alarm, but the light of your phone it too bright, and eyes don't want to open already.. argh!

I would like to have Siri for this purpose, since this particular situation happens to me just too often.

Interestingly, I use siri only once a day too and it's to tell it: wake me up at xx in the morning, just before falling asleep.

Looks like others are doing the same.
