- I assume you mean "univeral algebra", and not "algebra" as mathematicians

- In any event, I've never been able to understand the virtue of working
- within a mathematical model of computation which permits description of
- processes that cannot be carried out, even in principle, by any physical
- computing device. What is it that one intends to learn by application of
- these methods?
