This is something that steve jobs talked about in an interview that I cannot find at the moment. Its ironic coming from him, but he was talking about when a company truly begins to die. His theory was that when a company is founded, the people that made and designed the product/service are in positions of power. But as a company grows and lives on they get replaced with marketing people. They dont know how to make anything, but they do have that “line go up” mentality. Instead of making something better, the marketing and sales people find ways to sell worse things. Again, hilarious coming from him but i think he had a point.

Im not praising musk, and i really think he fucked up his lead on twitter and tesla, but he is very much similar to jobs. Neither musk nor jobs have done really any of the engineering work, but both have had their hands in some pretty remarkable tech. Musk with paypal, spacex, tesla. Again, im not saying hes a good engineer, he hasnt done anything, but to discredit those companies is unfair.
