First, it is the technology of how to apply knowledge to action to achieve goals…. That is what algorithms and programs are all about – frozen action to be thawed when needed.

The second ingredient is the miniaturization of the physical systems that have this ability for intelligent action.

Thus, computer technology differs from all other technologies precisely in providing the capability for an enchanted world:

For brakes that know how to stop on wet pavement

For instruments that can converse with their users

For bridges that watch out for the safety of those who cross them

For streetlights that care about those who stand under them – who know the way, so no

one need get lost

For little boxes that make out your income tax for you

In short, computer technology offers the possibility of incorporating intelligent behavior in all the nooks and crannies of our world. With it, we could build an enchanted land.
