Memory usage and the cost of DRAM. :-) From the Jargon File:

   All LISP functions and programs are expressions that return
   values; this, together with the high memory utilization of LISPs,
   gave rise to Alan Perlis's famous quip (itself a take on an Oscar
   Wilde quote) that "LISP programmers know the value of everything
   and the cost of nothing".

*My* signature is also a quote taken from the Jargon File (originally from
a book by Dijkstra).
