Why does everyone in this thread want to get rid of sleep? I like sleeping, and dreaming. 24-7 consciousness in the name of increased productivity sounds like a nightmare, no pun intended.
How can you enjoy something you're not conscious of? What you likely enjoy is the 5-30 minutes as you're falling asleep, and the 5-60 minutes as you're waking up.
If we could get the actual sleeping time to 1 minute, but keep the rest the same, surely that would be strictly better in terms of human utility.
