No. It has no competition, and is used by virtually every program that
uses python and performs array manipulation. I think it would probably be
part of the python standard library except for political issues (now

Many. I know that Distance uses it for FFT, for example. I believe
Calculate requires it as well, because it uses matplotlib for plotting,
and matplotlib requires numpy.

Yes. Numpy provides high-speed math for python.

Maybe, but numpy is not a good example. Virtually all science-oriented
programs using python make use of numpy.

Only if you don't mind that many Activities will mysteriously fail to launch.
