Yes. Definitely go with epigrams from works of fiction to guide engineering decisions.

You do not really understand something unless you can explain it to your grandmother.

- Albert Einstein

"The problem with quotes from the internet is it is hard to verify their authenticity"

- Abraham Lincoln

It does not then follow that when someone refuses to explain something to you like you are their grandmother that they do not really understand what they're talking about.

Also I'm pretty sure that's Diablo Cody's quote, not Einstein's.

There's a difference between explaining to an eight-year-old what you're doing and instructing that eight-year-old in how to do the same thing safely without spending a long time on his education.
