A huge amount of progress has been made in compilers, in terms of designing languages that implement powerful features in reasonable amounts of computing time; just try taking any modern Python or Ruby or C++ program and porting it to Altair BASIC
The “powerful features” of Python and Ruby are only barely catching up to Lisp, and as far as I know Lisp is still faster than both of them.

Except then you have to program in Lisp.
A fate worse than death.
Actually, SLIME is still the best debugger and IDE I’m aware of. Honorable mention to OSD, but that’d involve working in Java.
