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.

      Another part of the issue is if the laptop has two microphones, it can distinguish a place for low-freq sounds. The human head cannot locate low frequency sound sources such as a sub-woofer in a 2.1 system.
