I think a lot of us here are engineers who came from unrelated disciplines, or some even with no formal education at all beyond HS. Other fields could be the same way, if they could get over the cultural and authoritarian bureaucracies. Architecture has less scientific foundations, but it's nearly impossible to do without the prestige of an academic institution. Medicine is one of the most difficult fields, but I still think if you can demonstrate the same ability, you should be able to go to a residency program. Academia has an unfair grip on modern credentials, and I think that is one of the great things about tech. For example, some of the very most brilliant modern innovators abandoned academia, Musk, Gates and Newell come to mind.
