It might be you. But your profile says you have been programming since 1979, so I humbly defer to your experience. If you have made it this far without Lisp, I guess you don't need it, friend :-) Take it from a younger programmer, you don't have to grok lambda calculus to understand Lisp. I like Lisp, but I only have a vague notion of lambda calculus and all that academic gobbledygook. I still do not understand the Y combinator, nor I very much care to. CS theory is good and all, but it's importance is often overstated. Physicists are not engineers and engineers are not physicists; you can be a very effective programmer without knowing about Peano numbers and what monads are.
