I agree with the above.

And I definitely agree with that too.

I think that numpy.fft should be left there in its current state (although perhaps as deprecated). Now scipy.fft should have a good generic algorithm as default, and easily allow for different implementations to be accessed through the same interface.

Numerical algorithms should be part of the stack, for sure; but should they be part of numpy? I think its cleaner to have them in a separate package.

I would agree if it were not already there, but removing it (like Blas/Lapack) is out of the question for backward compatibility reason. Too much code depends on it.

Because sometimes we just need to compute a DFT, just like we sometimes

need to compute a sine or an exponential. It does that job perfectly well.

It is not always about speed. Just typing np.fft.fft(x) is convinient.
