tricolon
A sentence with three clearly defined parts of equal length, usually independent clauses.
By my count, that’s three tricolons in just over 100 words. It’s almost impossible to make A.I. stop saying “It’s not X, it’s Y” — unless you tell it to write a story, in which case it’ll drop the format for a more literary “No X. No Y. Just Z.”
Where it comes from
Learned borrowing from Ancient Greek τρικωλον (trikōlon), neuter of τρικωλος (trikōlos, “having three parts”). By surface analysis, tri- + colon.
