Thanks to multidimensionality, I'd say it's totally false. You can hire someone, or be hired by, someone who will raise your level via leadership, emotional skills, salesmanship, writing skills, and a million other "soft" things, besides the universe of technical skills that exist. I would think you only need someone to be better than you at one thing to make them a worthwhile hire or coworker.
