the direct chain I can see is

“can you string words to form a valid RSA key”

“I would hope so, [xkcd about password strength]”

“words are the least secure way to generate random bytes”

“Good luck remembering random bytes. That infographic is about memorable passwords.”

“You memorize your RSA keys?”

so between comments 2 and 3 and 4 I’d say it soundly went past the handcrafted RSA key stuff.
