Doesn't stop certain big tech companies from building giant campuses with cafeterias and housing so that employees can literally live, eat, and sleep at work.
If not for labor unions we would still be working 12+ hour days. The 8 hour workday and the weekend is all thanks to the courageous efforts of labor advocates.
Omg I actually had this same thought the other day and wrote it down.
I just thought about how cool it would be to not need to sleep. You could have a whole 8-or-so hours to do whatever you want. But then I realized that if we didn't need to sleep we would likely be required to work longer hours or be otherwise productive during those 8-or-so hours. It's crazy how arbitrary productivity really is.
https://www.powernapcomic.com/ deals with a fictional world where a drug makes this corporate dystopia possible but a small percentage of people cannot take the drug making them effectively disabled from a normal worker perspective.
On the other hand, it would feel pretty normal to us.
Perhaps even our time perception would be probably a bit different. As someone coming from world where bodies require about 8-9 hours of sleep, the perception of time is naturally affected (if not dictated) by having series of waking periods of about the same length every day.
If there was no such thing as sleep (which might be a bit different than just "not requiring sleep" as you suggest) then we'd just be conscious in one continuous chunk from birth to death. Given what problems our brains solve by sleep (learning, sorting memories / feelings), if the brains were to do these things continuously, the consciousness itself would probably be at least quite a bit different experience.
We kinda do it already, I can't be the only one that has taken "power naps" in my office instead of going home to sleep when a crisis hits at work. Hell, after the first one I bought a sleeping bag for those times.
