- 1. Although we are limited by processor speed, we are even more limited
- by the algorithms. A graph of speed in weather prediction as a function
- of time shows much more impressive jumps when better algorithms were
- debugged and adopted than you see when older algorithms were moved to
- faster computers.

- 2. Although we cannot forsee faster machines that are irrelevant, we
- can EASILY forsee fast machiens that are irrelevant because of the
- cost of their hardware, operating systems, compilers and application
- codes.
