To put things in perspective: at CRYPTO at some point in the past, I had a student stipend. I needed to send some documentation via email. I asked the person responsible, a prominent cryptography researcher (who will not be named), if they had a public key. The answer was, "No, I really should set one up but I'm just too busy."

When not even the researchers who run a top-tier cryptography conference are bothering, you know that it is not just about non-technical folks being clueless.
