Good and bad reasons to do an MBA

Dan Romero argues that an MBA is usually not a return-on-investment positive choice for people who want to work in tech, because its opportunity cost of two to four years away from the field is often underestimated. He says some reasons for pursuing one are legitimate, including fun, a career shift, and job "requirements" at certain firms, while reasons like "learning business," "the network," "the resume," and imitating successful MBA holders are weak. He writes that in most high-growth tech companies an MBA is at best neutral and at worst negative on a resume, since those companies favor two years of on-the-job learning over two years of academic learning.
