I&#x27;m guessing that he means that his work is closely related to arithmetic geometry (which I was once told was one of the hardest fields in pure math), and so someone with no background would have a lot of trouble getting it.  Presumably it takes even longer to become an expert in arithmetic geometry (15 years?).<p>I also happen to believe in 10x programmers, in fact I think I am one.  HN places a big emphasis on denying the importance of virtuosity or intelligence in programming, and characterizing it as a craft.  It&#x27;s very hard to argue against since nerds have had excessive modesty (often literally) beaten into them.  At least you get the occasional boastful athlete who says &quot;I&#x27;m just really talented&quot;.
