I recently came across this blog post [1] with the same title as that famous paper. But they switched out "scientist" for "programmer" and use a more graphical, less technical approach. It's probably better for this purpose.

EDIT: To clarify I mean "better than the famous paper". The blog post linked in this story is also very good, I'd say these two posts complement each other nicely.
