> EDIT2: typing at 90 wpm is 1,5 wps, or <10 bps according to Shannon (~1 bit per letter, 5 letters per word)
People can type way faster than 90 WPM, we talk about bitrate of the hardware here its the same even if you haven't practiced typing. And typing is still not what our consciousness is made to do, we have way higher bitrate than that when doing more native tasks such as running in the woods. You can't run in the woods without consciously thinking about each step and deciding where to put your foot next to not hurt your ankle and not collide with trees, that has a massive bitrate.
