This was 30+ years ago… I don’t know the details, but trust the source. The source used to teach at Carnegie Mellon. The point my friend made to me was that this guy was so good he never had to debug a program after he was done.

FWIW, apparently back before Intel released a particular 4 bit processor, this guy made an emulator and compiler for the chip so they could start writing code in anticipation of its release.

Once again, not direct experience… but trusted source.

Every CS department has these legendary tales that grow more hyperbolic over time (See "never" above.)

They are fun to tell!

lol, yes… it is indeed fun to share these stories.

Two alternate stories I didn’t tell:

First is about my two friends (both ridiculously smart) who in undergrad became the TAs for the Operating System class at Carnegie Mellon as undergrads (normally taught by grad students)… this is the hardest CS course taught there. As part of their summer prep, they wrote a new file system example… I believe based on a b-tree.

The next was my AI professor, Andrew Moore [0], he was legendary at the school… eventually becoming dean after doing a stint at Google (he has since stepped down). By far, he is the smartest person I have ever personally known. To give you context (and we did this regularly in his class), you could ask him a question on anything and he would pause, think about it, and come up with a well reasoned answer that would be both insightful and illuminating… from first principles. On any subject. You could not throw him (we tried). I am still in awe of him.

While I agree that legendary tales grow… they are almost always based on a kernel of truth. The reality is most people don’t often interact with folks at these levels. I was very lucky, and I have only interacted with a handful.
