It's obvious because () is a defined value, while bottom is not - per definitionem.
I wonder if this argument is circular.
I'm not aware of "defined" and "not defined" as more than informal terms.
They are informal. I could've written one is a terminating computation while the other is not.

Yes. If you've got a set of terminating computations, and it has multiple distinct elements, it generally doesn't *have* a least element. The P in CPO stands for Partial. jcc
