As in, the process in the brain? Because if I could turn on 'sleep mode' while maintaining enough consciousness to perform basic tasks/hobbies then several hours later turn off 'sleep mode' to regain full consciousness and feel fully rested then _YES_ sign me up for automated sleep.

Some people call that mode a meeting.

Or make sleep more efficient.

Sleep pods (or smart beds as they'll be more likely to be called if invented any time soon) that repair your body and inject you with nutrients, making you feel as good as new when you wake up, to the point of not needing sleep again for a few days.

Pretty sure you will always need sleep every day for optimal functioning. Unless you have nanobots cleaning things up maybe.

I could totally use the "making you feel as good as new when you wake up" part, though.
