That was a joke, right?

And? We are in the manufacturing industry. Nothing that is manufactured is an
exact replica of what you have in the screen. There is nothing wrong in
discretizing a model for manufacturing purposes so long it is accurate enough.

Yes, one should think about it... carefully. Replacing an existing standard
takes time and effort, and clear benefits must be obtained.
Given the current rate of development of RP technologies, it seems likely
the STL format will hit a dead end, but it is not clear, at least to me,
what should replace it.
