For artists, authors, and students, I think it’s only a matter of time until someone accuses you of using #AI in your art or essay, and you’d have to defend yourself or else get disqualified or penalized.
I think the best current defense against this is building evidence of the PROCESS of your work. If you write, enable version history in your word processor, and remember to save periodically. If you draw or paint digitally, make sure history is saved (some programs do this by default). If you code, ensure you have version control enabled, with meaningful comments about each commit.
When an accusation comes because someone uses some nonsensical “AI detector” program, show them a playback of your process. AI is (at least for now) unable to recreate the creative journey that gets to the end result, and probably never will, because there’s no money to be made doing that.
Version history is your best defense today. Consider enabling it, especially when your grade or income depends on it.
