Machines that were physically impossible or impractical to build become feasible. Design can be changed without retooling or manufacturing. Can concentrate on steps to be achieved without worrying about how steps will be realized physically. Advantages = Disadvantages Computer so powerful and so useful because it has eliminated many of physical constraints of previous machines. Both its blessing and its curse: + No longer have to worry about physical realization of our designs. c ￾✂✁✂✄☎✁✂✆☎✝✂✞✠✟✭✬ ✙✝✂✖✠✚✂✛✂✜✁✂✒✆✣✢✂✞✂✤✠✥✫✦✆☎★ − No longer have physical laws that limit the complexity of our designs
