Career in Marketing For Engineers

A paragraph from a book called Inside the Tornado by Geoffrey A. Moore goes as follow:

Marketing, in the engineering universe, is that place where the laws of utility are suspended. They are of two minds about this. On the one hand, if painting the product red sells more product, by all means paint it red. On the other hand, since there is no rational cause operating here, you cannot trust marketing, as anyone can see for themselves, since sometimes when they paint it red, it does not sell more. So marketing is essentially voodoo. It is for flakes. It is not a real discipline. It is a con job.

A lot has been said about how engineers view marketing as a career.

What do you think about this? Would you do a marketing job or should engineers stick to the technical field?
