But how do you really feel?

Truly, you are right. The old Bell Labs really did do consistently great stuff.

The folks there had a habit of correcting others' mistakes, not by attacking/criticizing but by example. One instance I recall was when some folks at Lawrence Berkeley Labs (iirc) decided they had to eliminate the feedback resistor in a nuclear science charge preamp to reduce noise. In the process they removed the FET input device from its case and shone light on it in bursts as needed to generate the compensatory charge. They got a significant noise improvement and attributed this to the resistor's absence.

Kern and Mackenzie of Bell showed that the main improvement was due to the elimination of the lossy borosilicate glass of the FET package, by making some FETs in lower loss headers, both alumina and boron nitride, and putting these in a standard preamp. They used a feedback resistor and still got comparable noise improvement to the Berkeley group.
 
This is not technical at all, but I wish they still did documentation with that fancy writing (ala Zobel's patent)... It's just so nice to look at. Science seems to get more respect when it looks good.
