4. The Changing Face of Computing
1980
80% of people in IT industry were programmers
CS curricula were based on the research interests of the faculty (automata, OS, compilers, AI, …
Almost no experimentation
2012
< 20% of people in IT are programmers
Industry and research interests have diverged
CS departments struggle to get people to teach compilers
Curricula have changed very little – added networks and graphics
These changes, and many more, mean that our academic field must change

7. Computing and Science All science requires validation
Computing almost invariably requires experimental validation
The behaviors, based on our imagination, must be validated
Because they come from our imagination, the validation must be empirical
Our goal is to solve problems with computing … the solutions must be demonstrated and validated through executing software
