I rather think the right word is clunky: one of the dev is attached to Server-Side Decoration/against CSD for some reason (none of his arguments make sense), so every stock app are difficult to read and taking unneeded screen space. It's just bad UX.
I don’t think any serious biologists agree with it. There is a hard physiological need to repair cellular damage from metabolism, UV (this a big deal in unicellular species), etc. If this theory was correct, and it is possible to do it entirely while awake, there would be species (apex predators in particular) that would have evolved without the need for it, like everything that is not a hard requirement. But this is not the case.
> Alternatively, perhaps elevated orexin levels during the day cause wakefulness such that you just don't need as much sleep, regardless of how efficient the sleep is.
As noted elsewhere ITT, there is a strong biological need for sleep, and its main role is very likely to reduce reactive oxygen species (though the amount needed vary by genetics)
Orexin levels increase the noradrenaline ones, which is one of the few antioxidants able to reach neurons (along with melatonin) and by this way also increase slow wave sleep, making it more efficient. So yes, this could be a way they would need less sleep.
Repairing cellular damage (mitochondrial and main DNA) from oxidation thanks to slower metabolism is the main reason.
On a side note taking vitamin E (an antioxidant that passes the blood-brain barrier) seems to have slightly reduced the need for sleep for me.
Your comment takes 630 bits, the screenshot of your comment on my computer takes 2.1 MB, about 218k times the size. Either this is a compute overhead the LLM has to do before it can think about the meaning of the text, or if it's a E2E feedforward architecture, less thinking about it.
This is simple for us because neurons in the retina pre-process its stream so that less than 0.8 % is sent to the visual cortex and because we have evolved to very efficiently and quickly extract meaning from our vision. This is a prime example of the Moravec's paradox.
Because of real-timeness (you don't need to refresh a webpage, you can see if someone is typing). I am not aware of a forum software that have this feature (I don't know them well, so I can be mistaken). But most of the time you don't need it.
