this is especially relevant to the software industry. "10x" coders may well just be people who pump the breaks on working long hours and confine themselves to working the number of hours that they can be maximally productive. work less to get more important work done, as it were.
Excellent point -- I completely agree. While there are several different types of coders, I think all too often you have that one person on the team that busies themselves to the point of being wholly unproductive. Applying the "10X" tag to those that work more diligently is probably the best use of "10X" I've seen in a while.
