Interesting comment from Rogaway on clipart in cryptography presentations:

"There is a long tradition of cutesiness in our field.

People spin fun and fanciful stories. Protocol participants are a caricatured Alice and Bob. Adversaries are little devils, complete with horns and a pitchfork. Some crypto talks are so packed with clip-art you can hardly find the content. I have never liked this, but, after the Snowden revelations, it started to vex me like never before."

Reminds me of the magical internet money wizard. I was the grumpy old git back in the day who complained that this was a dreadful meme, and I still stand by it. It conveys literally the exact opposite of what you should convey to curious newcomers about Bitcoin imo. Literally nobody agreed with me though 😆
