The following post is just an opinion and is slightly off the original
topic. Maybe someone else will share their opinion and enlighten me?

I have come to think of Mathematica more as a research tool than as a
large scale number crunching package. Perhaps cryptography is
different, but it seems like tasks that do not take up much memory or
computer time in commercial solvers for, lets say, finite element
analysis take up way much more memory and time in Mathematica. I know
people may be thinking that I should use Mathematica's sparse solvers
and arrays for memory and speed improvements. I say to them, you are
right! Commercial solvers use those methods by default -- the problems
people typically solve in FEA require those methods to have any chance
of running on a PC. Then we move to problems of interface --
Mathematica has a wonderful front end, but it is not a good CAD/CAE
interface.

None of the above is really a problem. There is much to be said about
using the right tool for the job at hand. Still, I think it is human
to yearn for one tool to do everything.
Regards,
