Students + chatgpt will figure out what tools colleges are using to figure out if the essay was AI generated or not + why.There is an art to it and you get better with practice, and in addition the algorithm will get better all the time. Trust me, college and high school kids are using it right now, and whatever apps are out there to supposedly catch them aren't catching them. For now it is free, but once everyone gets hooked it will come with a cost and the digital divide will grow larger once again.
Then they'll both modify it enough to get past the tools used to identify fakes.
Even now students are likely using AI tools to create an essay then rewriting it + but keeping the overall structure.
