I also think it has something to tell us computer scientists about abstraction.

For those with a hardware background, more details tend to be the comfort zone, while for those with a software background like myself, we are quite comfortable with less details. I recently did some experiments about the use of quite low levels of hardware modeling details for early architecture exploration and system specification.
