EB as a term is new, the specialization is not.
Most here are engineers with a BS/BA. Maybe a MA. And fewer still with a PhD. Not that education is everything, but it's certainly "years specializing."
Compare that to the track of a typical specialist md:
After your undergrad degree you've got.... 4 years in med school. 4-6 years in residency. Plus a 1-3 year fellowship.
Long story short, what's the credible alternative to relying on multiple expert opinions? Are educated (engineers/lawyers/etc) ordering tests based on research they really don't understand on themselves a better? By what evidence?
