Or nearly any other field, e.g., mechanical engineering, electrical engineering, chemistry/chemical engineering, nearly any of the sciences involved in the medical field (from pharmacology to psychology to name a few). Even "softer" fields like law and literature have present day geniuses pioneering new ground.

I understand that HackerNews is tech centered, but some times when I read "the best minds of my generation are doing X" I wonder if the commenter can see the flashes of brilliance shining beyond their field or what they know as "tech."

Totally agree. I'm surprised I was downvoted for my comment?
