I find this really hard to believe. If it were really possible then people could do it with their ears, and they would be doing it and showing off that they can do it. The human ear (and brain) are really, really good at finding patterns and getting signal out of noise.
You're really surprised that computers can outperform humans at pattern recognition?
Yes. Humans have fantastic audio and video processing abilities, particularly picking out signal from noise. Even now human operators listen to sonar signals on submarines. There's a reason for that.
Part of the issue with keyboard audio is that it's very "noisy". It's like comparing two instances of white-ish noise. Statistics would be able to discern the instances immediately, but a human probably wouldn't.

Computers are better at stuff than humans? Impossible! I am the king of math, no machine beats me in calculating numbers!
Piano players can do it if the typist uses a piano keyboard. Also 88 keys but arranged in one row.
I think that a person could do this too with enough training.
This isn't new. Soviet listened to typewiters back in the 1970s.
