I think this is a great analogy because both code and cleanliness carry similar social consequences. If you live by yourself, you can be as messy as you want.

I think this is a great analogy because both code and cleanliness carry similar social consequences. If you live by yourself, you can be as messy as you want. It's only a problem if your mess becomes a biohazard for your neighbors that you have to take care of it. Otherwise, if you're happy with your mess, that's fine. If you live with other people, your mess in the common area becomes their mess. That's a problem if other people do not like your mess. There needs to be agreed upon standard by those living together. Eventually, the mess will inhibit your ability to work productively regardless of the situation. I guess you can always throw out dirty dishes and buy new ones, but there is a cost to bear.
