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
mostly resolved).
It's not used as much as you think:
1!bernie@giskard:~$ LANG=C rpm -e numpy
error: Failed dependencies:
numpy is needed by (installed) pygame-1.8.1-7.fc12.x86_64
bernie@giskard:~$ rpm -qa | grep python | wc -l
93
It's also one of the worst startup time offenders I've ever seen in
Python: with hot caches, it takes 300ms on a fast computer (~2 seconds
on an XO). A lot longer if you have to actually fetch it from disk
along with its unique dependencies.

Yes. Numpy provides high-speed math for python.
high-speed *advanced* math functions.
