Not at all. For example, I have designed a low power regulator with a
PSRR 10 times better what any of the competition at its power level. I a
chieved this by using 2 simple techniques probably about 25 years old,
but apparently no one else, in this particular, field was using,
preseumable becuse they did not know the basics. In fact I explicitly
rejected a newer, patented circuit that was suggested to me because the
patented circuit, whilst novel, had no net benefit. Newness in most
cases has zero practical value.

You have simply missed the point. *If* you are being *paid* to do
engineering and develop products, then your moral and contractual
obligation is to maximise the paying companies profits. If you want to
goof off and do you own thing, do it with your own time and money. In
addition, I have made no comment here on the type of work I personally
prefer to do.

None of this has anything to do with engineering. Secondly, volts and
amps have not changed since the existence of the universe. I can indeed
build a flying car with an existing screwdriver.

Complete bullshit. You just haven't a clue how the world works have you.
