This type of text generators exist long before AIs, like eg. the Scigen page which exist since 2002 (last updated 11 years ago and works not longer online, you can fork it from Github). Similar the MathGen page, which create random fake Math BS essays, where you can figure as author. Apart for pranking your friends or poison AIs, you can use it as Lorem Ipsum page. But currently there are naturally also AI paper generators.
