I don't know how scientifically factual this is, it was presented as such but it's hard to believe it in a literal sense but there's a Benn Jordan video called "How The World SOUNDS To Animals" about how different animals perceive time differently. Like flies perceive life many times more slowly than we do which is, allegedly, why they seem to get away when we swat at them, no matter how quickly we move.

If that's true, I'd expect they just perceive time more slowly than we do which is why they're able to appear so much more quick. I still agree they've got a lot going on in those brains I just think this aspect of it is interesting!

Humans have reaction times on the order of 100-200ms. But interestingly if you measure reaction by you moving your hands or torso about 10%-20% of that time is just the time it takes for the signal to travel from your brain to the right muscle. Nerves aren't all that fast. That's why many reflexes happen outside the brain, closer to the relevant body part.

With that in mind, it would make a lot of sense if time perception scaled with body size. If you are a big elephant signals need to travel very far, and your muscles have to overcome a lot of inertia. If you can't react quickly anyways you don't need to perceive time as quickly. A fly has little inertia, fast signal times because of the short distances, fast processing because there just are fewer neurons, so there is more advantage to perceiving time more quickly

I can imagine the same would apply to any Super-intelligence. To the singularity, time would simply pass immensely slow because of the parallel computation power, which to us humans on the other hand would look super intelligent.
That's a really interesting way to put it! Thank you! That makes a lot of sense!
Flies feel the rush of air from our oncoming hand and get out of the way, just like we look up from our book (phone, these days) when we feel air from the oncoming subway train we are waiting for.

The secret to killing flies is that they have to fly up first before they can fly away, so you (slowly) put your hands in front and behind them and "clap" them. They feel the air and lift off, right into the center of your oncoming hands.
