I agree.  There seems to be a rush to convert Lisp systems to C (or
C++) just at the time when the standard complaints about the size and
speed of Lisp implementations are becoming irrelevant.  Memory really
*is* cheap - I just bought 16Mb for my home machine for less than 600
pounds - and processor speeds are increasing so that if you need to
double your speed the easiest thing to do is wait a year rather than
rewrite in C.  Add to this the advantages of built-in garbage
collection and extension language, and Lisp becomes the obvious
choice.
