Math is a special sort of language, I don't think that Spanish is less complex.
Lets not sell each other short, we have each chosen disaplines that are difficult to learn and practice , that we each went in diffrent directions says nothing about how hard we worked or how well we mastered the difficultys which are all diffrent.
I am not really happy that our little club has gotten so small, it needs to be bigger and more varied rather than smaller and more homogonous.
But I do note that all of the members that have elected to stay seem to be quite intelligent, that is self selection and might be very positive.
What can happen to make our discussions more interesting , and our group more inclusive , and our number increase a bit?
There are things I like about a small group , but any smaller than we have now , won't produce debate.
