The more predictable a work process becomes, the quicker people can do it too.
Our issue is with correctness, that is something we not even think about in computers. So, it's not really surprising that this completely different issue has different constraints than speed.

The most highly-voted question on Stack Overflow[1] relates to branch predictability. There's an almost 10× speed-up when the branch predictor of the asker's CPU is fully engaged.
Modern branch predictors are extremely powerful, with TAGE and perceptrons achieving 99.5%+ prediction accuracy.
