Sales isn't an assembly line
Great software companies require someone to build the product, and someone to bring it into the world. We've spent decades turning product-building into a highly regarded profession with clear career paths, idolised practitioners, and a culture that treats building as the highest-status work there is. Meanwhile, bringing the product into the world we industrialised to the lowest common denominator.
This is why the sharpest people you know can tell you exactly how to become a great engineer, yet almost none of them have ever seriously considered sales.
