Well, maybe he did, but again, in my view a good circuit is not one that
has some unusual feature or some sort of "clever" approach. The *best*
approach are circuits that are bog standard, easily understood by simple
inspection and meet spec. "Best" being defined as the ability to ship
reliable product with few returns, in a timely time to market manner.
This is what we get paid to do, not to produce aesthetically pleasing
circuits that we like to impress people with.
I am a bit hard on this issue as I feel that so many have simply the
wrong view on what being an EE is all about. We get paid to make
*profit* for the companies that employ us, not to produce elegant
circuits. The contractual duty therefore is to maximise profit.
