it's an (maybe the most) extreme example of something which is "gen AI" but not problematic
and as such a naive "rule" saying "no gen AI at all" is a pretty bad competition rule design
Reductio ad absurdum is a form of logic which takes an argument to its logical conclusion in order to demonstrate that it is absurd if it were to be taken on its face. Whether or not anyone applies it that way in reality is irrelevant.
some pretty decent "line smoothing" algorithm are technically gen AI but have non of the ethical issues
You'd have to cite an actual example of something this ridiculous. Non gen-AI algorithms have been line smoothing just fine for 2 decades now for less than a trillionth of the resources required to use gen AI for the same task.
there is a whole basked of technologies which you can label as "gen AI" but which have non of the problems why people hate "gen AI"
as a very dump example, some pretty decent "line smoothing" algorithm are technically gen AI but have non of the ethical issues
