Let's take names. I have diacritics in mine and an appalling number of computer systems can't handle them properly. Should I drop them completely and loose a part of my language in the process? Or deal with more □? firstName + lastName is another, where our idea of naming is forces on to others with a different system.

Dates. The US sets weeks from Sun-Sat and much of US software defaults to it, even when it should know that in my locale Mon-Sun is the default. In some cases I can't even change it. And don't get me started on MM-DD-YYYY.

Processes. Talking to a human is easy. There is leeway. A computer says no. Now I have to conform.

More broadly, we humans do fantastically well with ambiguity. Modelling ambiguity is tricky, after all, computers are extremely fast morons. So that ambiguity gets lost.
