Robin Hanson: You really think an office worker with modern computer tools is only 10% more productive than one with 1950-era non-computer tools? Even at the task of creating better computer tools?
Not in the general case. However, I’ve known people who use these modern computer tools to take ages typesetting a simple document, playing with fonts, colours and styles, and have managed to get very little work done. I’ve even known people who’ve managed to get negative work done due to their incompetence in using computers.
