Sorry, where is the OP critiquing the individual? I can't see it.
Seventies-era Xerox PARC cultivated a deliberately confrontational environment for its researchers. They managed to accomplish some great things.
"They managed to accomplish some great things" in spite of being jerks to each other.
Imagine what they could've accomplished if they had empathy and were collegial with each other.
When you consider, other people took their ideas and build companies worth hundreds of billions out of them, but they themselves didn't. hmmm...
Edit: Also, thank you for posting the text. I came to the comments hoping this had been done.
