Eric Weinstein says some crazy stuff, but I remember hearing him once say that the best debate strategy for Republicans would be to mention the "noo-kyoo-lar" family, and let them correct you to "nuclear". Then you win because the other side looks like pedants and elitists. This "octopi" is definitely such a word.
Side note: all this off-topic pedantry about octopi vs octopuses is an old discussion already resolved. It is clouding discussion about what the full implications of what it actually means to treat octopus (ha!) as sentient.
I don't think the Democrats have cornered the market on pedantry just yet.
I realize they are being cheeky but the ironic thing is "ignorance of N languages" is one of the primary drivers of linguistic cross-pollenation and drift. Taking loanwords, shoehorning them into your phonology, writing, and grammar is just how these things work.
