This pattern seems to be nearly trivial for modern man, but it is still important and useful in inventive designing. It can be formulated thus  

An engineering system evolves in the direction of decreased human involvement. 

We can easily provide many examples. One of them is the evolution of heating, which began several thousand years ago. This evolution began with 

Pattern No. 8 is also useful in various inventive design situations because it reminds us that additional automation should always be considered, particularly when we want not only to follow existing trends but also to create them, as should be the mission of all inventive engineers.
