Elon's and Manoj's statements caught my interest since hiring MBA-types is assumed to be a standard move for entrepreneurs who have completed the exploratory phase of reaching product-market-fit and are trying to scale up quickly.

Even if you're highly skilled in entrepreneurial and/or executive tasks, you'll need somebody who deals with monitoring, dissemination and handling low-key disturbances. To be honest, I always assumed that you should hire MBAs for this, but now I'm a little more wary.
