> It matters because ugly code is probably also slow code

This is a very bad assumption, that's highly dependent on subjective and overly-broad terms like "ugly" and "slow".

Optimized assembly code is ugly, but it's also probably faster than what a human would choose to write.

Linguists used to have this human-understandably-sized set of speech units called phonemes. Once we abandoned those for finer-grained pieces that were too many and complicated for a human to grasp, speech recognition got better.

Understandable by a human may be a fundamental limitation on the power of our models.
