Whenever someone says there's no such thing as a 10x programmer, I point them to Fabrice and they usually change their mind.
It's kind of crazy it ever became some accepted world view, given how every field has a 10xer that is rather famous for it, whether it be someone who dominates in sport, an academic like Paul Erdős or Euler, a programmer like Fabrice or Linus Torvalds, a leader like Napoleon , or any number of famous inventors throughout history.
