Did you actually read the article? I don’t think the author really expects you to memorize anything. The last part about bathroom breaks emphasized the already non-serious style. Instead, the article teaches the reader about what a Mersenne prime is, what special property it has to make it actually possible to remember this very very long number (perhaps surprisingly, if you did not know about Mersenne primes already), and did give me a few neat, new ideas on how to memorize numbers in general. It’s just a fun read. No need for the soap box, really.
