Something that I've found deeply troubling with the PhD education and training and how it interfaces in industry, having worked with a very large number of PhDs over the years, is the seeming inability for PhD-level staff to simply edit their work and ship things on time.
I know this is a large generalization, but I could comfortably say this is a predominant trait among maybe 70-80% of the folks I've worked with. On the surface it seems like there's something in the training for PhD staff that seems to kill the ability to self-regulate that's a very good thing when pursuing the unknown, but an excruciating pattern to deal with in industry where budgets and shipping times are primary importance.
Seeing this in action, and knowing I have no interest in working in academia, has been the primary reason I haven't pursued one myself. I don't want to be "broken" by training.
I get to pursue all of the R&D I can handle already working in an R&D lab -- with the usual publication, patent, ship to customers that it all entails. So I'm not starving for interesting things to pursue.
