I have a physics degree so I'm more than aquainted with the split between physics and engineering/marketing.. You'd be drop-jawed if you saw some prototypes for stuff that came out of the labs even 25years ago.. After that, profitability, and mass production difficulties spoil the fun..
One of the biggest exceptions is the DVD.. Those things were raced through development, they dropped production costs/time by over 99% compared with video cassettes, and back when we could still get vhs, the dvd's still cost more..
