This quote can be interpreted in an intelligence-positive way, to encourage you to learn by writing the cleverest possible code. Then, when you get to debug it, you will be forced to improve your skills. This interpretation is called Kernighan's lever  and it is very beautiful. The alternative is a life of boredom where you don't learn anything new.
”Isn’t this a wonderful learning opportunity for all of us”
Debugging time is never a good time to start honing new skills.
It sounds like spaghetti code but even worse because it’s covered with a messy layer of beans and guacamole and wrapped in layers of tortilla.
Next up: some doofus who learned high-order Haskell in middle school, and takes offense of me calling it complicated.
Now that's an impressive logical leap.
When I try something new, usually what I learn is not that my assumptions were correct, but the more interesting part is where my assumptions were wrong. This usually only becomes apparent either when writing the code, or in some of the more interesting cases, when debugging.
I would claim that any clever final result can be accomplished without any need for intermediate cleverness. Things that look clever to other people but are intuitive to you might be OK. Things that look clever to you should be avoided when possible.
