Yeah, it only teaches you about term rewriting, boolean logic, iteration vs. recursion, algorithm complexity, higher-order functions, data structure design, closures, generics, statefulness, environments, mutability, concurrency, stream processing, modularity, interpreter design and implementaion, lazy evaluation, nondeterminism, logic programming (i.e. search/constraint), low level computer architecture, memory models, and the design and implementation of virtual machines, garbage collectors, and compilers. Just a total waste of time unless you're doing Lisp.
