Honestly half the reason I argue for rubocop is to avoid having readability discussions with other devs when I don't have strong opinions. I've discovered that I am nonplussed by patterns that leave other devs downright emotional and it's just not worth the effort to discuss, especially when 99% of readability issues (eg naming) are absolutely undetectable to rubocop. Having a consistent style allows splitting styling and, erm, more fruitful readability discussions.

Anyway remember you're writing code, not poetry. The inclination to act as if you're writing the latter without any kind of cost/benefit analysis is a major reason I dislike working with ruby devs. If only I were actually writing for powerpoint slides rather than for concrete business ends!
