It also forced them to spend a lot of money achieving these goals.

It also make anyone else maintaining or porting the program spend weeks (read
thousands of dollars) just trying to understand a small program in order to
accomplish the task.

The also produce a functionally equivalent program in far less time which is
available on far more machines.  (Boss, I can spend eight more weeks and double
the speed of program.  Of course, then it will only run on the 40 or so
machines which are exactly like our development machine.)

Not fast, cheap.

Which goes to show that raw performance is not highly valued by customers.

Raw speed is only one aspect of advances in the industry.  Hardware
concentrates on speed while software concentrates on functionality.  (Mr.
Customer, I am giving you a fast sort, but I do not have time to implement
a backup utility.)
