Extreme Sleep deprived people did hallucinate. Nature may give us some hints to improve "AI" reliability.
It was a mistake to use the term “hallucinate” in AI. It’s a decent metaphor but it’s best to avoid terms prone to anthropomorphism.

I haven't used an alarm clock in 20 years and wake up within the same 5-10 minute window almost every day. I have a friend that will just sleep through multiple alarms. But he can also just fall asleep in 10 minutes on an airplane and I can't sleep at all on a plane. He also takes lots of naps and I never take a nap unless I'm sick. The worst feeling to me is waking up from some external noise. I just feel so groggy…
Wasn't there supposed to be a smart watch out there you could set a window of time you wanted to wake up like "between 6:30 and 7:00" where it would use the sleep tracking to pick the optimal time to wake you up like at the end of a REM cycle? I feel like I must have hallucinated this because I'm wearing a smart watch (fitbit) now and no such feature exists.

Whatever sleep does, it's something nature has had a tough time optimizing out despite the extreme vulnerability it creates and the sacrifice of a little under half an organism's waking time. That should tell us it's something incredibly important that's hard to do any other way. Edit: on the other hand... if Earth had two suns and rarely had periods of darkness, you wonder if maybe there would have been more evoluti…

Apple Watch does this.
Relevant to this, people with a genetic mutation that adversely affects sleep end up developing dementia and dying early: https://my.clevelandclinic.org/health/diseases/25001-fatal-f...
I've wondered if anyone's ever looked at inducing long periods of sleep as an early dementia mitigation.
Some people seem to need a lot less sleep than others with no deleterious health effects. It would be very interesting to find out why.
Is that actually the case? do we have long term data on these people? or are we just going off of "I feel fine on 5 hours of sleep" stories? Or are you only referring to day to day health effects?

Alternately, sleep is the optimal ultra-high-efficiency survival state and wakefulness only exists to give creatures enough time to get their affairs in order so that they can safely return to dormancy. It's easy to think of sleep as a compromise to be defeated because we're culturally preoccupied with the achievements and pleasures of wakefulness, but that's really just us claiming personal preference for one narrow…
Which doesn't mean that's the only thing sleep is good for, evolution doesn't believe in separating concerns, but it's definitely a thing it does.
