Right, but you can't become a doctor without spending many thousands of hours and hundreds of thousands of dollars gaining credentials. But you can become a highly compensated software engineer by spending a miserable day answering pointless questions on a whiteboard. I would personally prefer the credentialing approach because at this point it would be easy for me to get the credentials. But the low barrier to entry also has advantages.

For that matter, I'm not sure that the way medical education is done is something to aspire to. Years and years of exhausting sleepless tedious grind, at the expense of any instruction on deductive thinking or bedside manner; if at the end of it all they can't even draw the Krebs cycle from memory, then what the hell is the point?

Ha! My hobby is pharmacology and I’m always having to refresh myself on various steps of Krebs. We need a Ninja Nerd[0] for CS I guess, I’ve found it incredible.
