There will always be those nitty-gritty situations where size and versatility
are the main issues. 

I can't see having a real-time situation wait for a LISP garbage collection, 
do you? 

No matter how big the "micros" become, there will always be the small 
machines, whether it be from a cost standpoint or due to necessary development 
time. There is always a need for distributed control, embedded control, 
self-contained diagnostic tools and small computer development systems. 
FORTH reduces the design cycle to the point where complex, compact
applications are quite easy to build - for a single software engineer.
FORTH is one of the last, true, seat-of-the-pants languages where a single
software engineer can build something quite large, quickly and unaided.

LISP is one of the other languages that this is true of as well; however, LISP
is not as simple as FORTH internally and performance is definitely an issue.
I would think it would be difficult to embed assembly language code amongst
LISP object code. Garbage collection and memory management are major 
complexities and are absolutely "too much" for a real-time environment.
