>>13695409>What is the actual purpose of sleep?There's no single reason for it. It's partly that developing really good scotopic vision didn't yield enough of a evolutionary advantage for our ancestors, it was simply better to stay put.
Staying put means you burn less energy, which is more efficiently spent doing tasks in the daytime.
It also means you don't get into harms way by walking around in the dark.
>What does it actually do for us?Aside from the fact that it prevents exacerbation of injuries because you're lying virtually motionless which means that you can't agitate or further damage tissues as much as you would if you were walking around. Anabolic growth hormones are also secreted during sleep and a bunch of other things you can fucking read on wikipedia if you weren't so lazy.
>Could we eliminate the feeling of being tired, never needing sleep, and still function perfectly fine?Probably not, it's the same problem with legacy technologies - optimal human processing currently rests on top of a long of processes that require sleep. You need to change those processes too to eliminate the need for sleep.
