Rosen

Nick Thompson
I havent been able to follow the conversation but the following caught my
eye

>Machines are the produce of a self-consistent model

Please dont forget the whip sockets on the early model A's.

Rosen

Phil Henshaw-2
Right, it was well understood that people would not buy a car unless it made
provision for being pulled by a horse!!  

It's an excellent point, that many of the user interface features of the
controlled systems of machines are themselves intended for people coping
with an out of control world where lots of things behave in altogether new
ways unexpectedly.
