The guy has brains to burn of course, but tbh, it's simply about motivation. Medicine is a grind, more than an intellectual exercise. If you have the brains for actual tech there's no doubt you have the requisite intelligence. The only barrier is the stamina for the grind. I know I couldn't do it. Not as I am now. Maybe in the future. I couldn't say for sure, given I'm not clairvoyant.

I agree that you should give serious pause. Probably the most serious pause of your life, but still. I wouldn't shy away too quickly. When you know, you know.
