So a couple of Corinthians walk into a bar

17. No, they do not. However the people who use them do.

That's why there are so many programming languages. That's why the users of those computers enter numerical date and see results in arabic numbers. The binary nature of computers is due to their use of simple two state semiconductors for everything. For them to be useful, it all has to be converted into something that people can use to provide input and get information from those binary systems.

Through my adult life, I have had to learn to think in multiple bases for mathematics. Most of those were powers of 2. Other number bases were less useful, but interesting in their own rights.

However, it's not particularly useful in the real world to use any number base but 10. We do that because of our five-digit pairs of hands and feet, the earliest tallying devices of all. If we had evolved with 6 fingers and toes, we'd be using base 12, most likely, as is used in some systems of measurement.

In many way, we're still counting on our fingers, and base 10 makes arithmetic pretty easy, really. So, it's a good compromise.

However, most of us can still tally on paper. I still use a tally system for counting large piles of discreet objects as I move them into piles of some size or another. We're also pretty good at instantly identifying groups of five things. Watching a pharmacy technician count pills manually, you'll usually see them separating out five at a time.

Computers are good at displaying any data in any form you wish, if the programming is designed to do so. Like most educated people, I use scientific exponential notation for very large and very small numbers, using powers of 10 to abbreviate them.

I never use anything other than base 10 in daily life, though. I could, but can't think of any practical reason to do so. I work with common fractions, of course, and am quite comfortable with measurement systems that are 12 or 16 based, but that's a specialized thing and should probably be replaced by metric measurements, in my opinion.
