My previous post gave examples of how David Souter and Donald Knuth chose not to use some common technologies. John Venier left an insightful comment.
I think the avoidance of technology in these cases is really an avoidance of distraction. These same fellows would probably not keep a parrot in their office if it screeched every couple of minutes, regardless of their affinity for birds.
I believe he’s right. My intention was to write more broadly about how tools influence our thinking, but the examples I gave were only about one kind of influence: distraction.
