They raise you maximum speed, iirc.

It’s pretty good. I liked it a lot. There is this theme of fighting with and between gods (uploaded humans) and has a pretty good ending that made me want to rewatch it.

It is unfortunately only legally available in Australia and New Zealand from what I know, so you probably have to look around for another way to see it if your not from there.

This remind me of a cartoon series that I recently watched called Pantheon, where they upload a humans brain and consciousness into a computer.
