Well, amazing is relative. To underserved kids in poor school districts yeah his skills are probably amazing. And while an MIT Physics degree doesn't explicitly teach software engineering craftsmanship, his first employer Jane Street has high standards for that, and may have, depending on what he actually did there.
But compared to, say, Jeff Dean, his skills are garbage, tofu-dreg, and devoid of any real craftsmanshift or integrity. Pick your point on the continuum.
But I'd rather have high-skilled conmen like Sam, Michael Milken, etc. answering for their crimes and rehabilitating by helping others and being constructive, than wasting away in jail, and potentially teaching other criminals there, or becoming more criminal themselves.
