I would actually love to see some AI homework failures from the sciences.
My encounters with AI generated by students have been exclusively on writing assignments & the mainstream moral panic has been about the college essay.
I encourage you to ask a science or social science colleague about the graphs, charts, & diagrams they've been receiving. 😳🫣🤢
