I guess when you attempt to keep up with, hold schmoozing sessions with, politick, etc. with a bunch of companies where 95% of them will end up doing nothing actually valuable for the human race (and only 70% doing it on purpose to climb the VC ladder), you are not actually getting anything real done, and your brain then readily adapts itself to being an efficient but almost non-sentient gossip processor.
At first it resists, hitting you with stress signals and thoughts of pointlessness and depression. Weaker, or more accurately, less indoctrinated individuals would stop at this point and give their lives a once over.
Not in this case. Eventually, article by article, event by event, pointless rambling after pointless busywork session, Michael Arrington's brain capitulates: "Welp, I guess you didn't really need these memory networks after all, let's clear em out so you can be uhh, 3% more sensitive to inane tech gossip-related stimuli. Have a nice life!"
