Thanks for sharing this conversation. I am with Percy in most of the
points (except that I call Analitza a CAS library so my terminology
might be wrong).

This. I am willing to mentor one idea during GSoC[0] to evaluate the
use of Analitza in Kig to simplify the code around solving
intersection of curves etc. The last time I checked with Aleix (and
that was like a year and some months ago, so it might have changed),
Analitza didn't have these features so I tried using GiNaC and got
stuck at some point.

This is the one point I don't agree with: improving Analitza won't
address this use case directly - and as a Latin American, I am very
familiar with this use case. Right now, you can install KAlgebra on
all of those computers and my guess is KAlgebra works just fine for
their needs. Improving Analitza will make it easier for people to
develop new math applications with a very specific purpose around KDE
technology. Arguably, they can do the same using GiNaC, but that's
another story. Again, I am all in favor of improving Analitza, I just
don't think this is a proper argument.
