cache - compilation, interpretation, representation and cache management

This is a collection of ideas about what I perceive as the main
problem in IT management: the fact that compilation takes a long time,
and the fact that management of compilation results (caches) is a hard
problem in itself.

There has to be some better way to look at this.

As a side goal, is it possible to build a "personal IT system" that
takes these ideas into consideration?
