But 1960's Lisp was as bare-bones as it was high-level; you still had to wrote almost everything yourself from scratch.
Computerized math is the same today. No one wants to write everything they need from scratch, unless they're working in a genuinely self-contained (i.e. 'synthetic') subfield where the prereqs are inherently manageable. See programming languages (with their POPLmark challenge) and homotopy-type-theory as examples of such where computerization is indeed making quick progress.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
