I have a hard time imagining this will ever become a reality; the need for sleep is fairly deeply hard-coded in how our brains operate, and I believe it's also needed for some more basic cellular functions.

It's not binary I guess (sleep "once a week" is less than "sleep once a day"), but even some incremental improvements seem very far off.

One also has to wonder if it's actually desirable to have less sleep and be "on" with fewer or no breaks.
