Getting promoted to your level of incompetence now has a behavioral definition: The Peter Principle. Avoid overextending your workers so that they are still productive for your company. Demotion is better than getting fired for incompetence. If you are a startup getting core workers for your project, it is better to pay specialists who are very good at what they do than getting people who need to grow into their positions. Start-ups have a very small window to make a dream a success. Get and pay creative people who are the best at what they do from the start. Always. Less worries if you do.
