Nah, no fight there, keep metric, just make it base 8  | ||

I mean that the elegance of e^(i pi) = -1 is a bit lost in e^(i tau) = 1, of course it's still true  but it isn't as obvious, while e^(i pi) = -1 instantly implies e^(i tau) = 1 (by squaring) | ||

 Seriously, who cares? If a factor of 2 troubles you, maybe you shouldn't dabble in mathematics. This change in nomenclature would produce misunderstandings for years to come, it's just not worth it for some insignificant advantages. | ||

Because everyone else uses it? If so then how about people stop speaking any language other than Chinese, Spanish and English, because those are the top 3 languages spoken in the world (in terms of native speakers.) And the fields that matter (science/military) use international units anyways. | ||

How would having tau and pi hurt anything? Surely they could co-exist peacefully? | ||

You just replace the general definitions with tau to make it more intuitive. How would having tau and pi hurt anything? Surely they could co-exist peacefully? Making 2 constants out of one is incredibly inefficient. | ||
