It seems to me that these discussions miss one point of foundations:
the characterization of the various elements. It may be just as new
(and wonderful) to know two old things are related in new and perhaps
surprising ways as it is to have some totally new concept emerge. This
nattering about someone else's area is not as important as another
seems unproductive --- gleefully enforced by our deans and presidents
and funding agencies --- but unproductive, none the less.
My take in watching all this: it's like the 20s and 30s when people
were looking for *the* foundation: logicists, set theorists,
etc. Ultimately, won't all this work show that "mathematics" is
categorical at the foundation --- that all these metaphysical
assumptions lead to a class of structures that are inherently equivalent?
Isn't that a good question for foundations of both mathematics in general
and the subset I'm interested in: computing?
