indeed. there's nothing spectacular about a base 2 system, except how inconvenient it would be. the babylonians were using base 60 systems thousands of years ago. take that for obtuse.

the question as to "why?" is interesting, because it's sort of like asking why people would uninvent the wheel. base 10 took a long time to come up (it's not as simple as how many fingers we have, that doesn't add up to historical evidence, it was more about religion and mysticism in the early days) with and is really quite ingenious when you break it all apart. why bother?
