What's the reason for this?
Media is the most likely thing I'd consider using AI for as part of a contribution to an open source project.
My code would be hand crafted by me. Any AI use would be similar to Google use: a way to search for examples and explanations if I'm unclear on something. Said examples and explanations would then be read, and after I understand what is going on I'd write my code.
Any documentation I contributed would also be hand written. However, if I wanted to include a diagram in that documentation I might give AI a try. It can't be worse than my zero talent attempts to make something in OmniGraffle or worse a photograph of my attempt to draw a nice diagram on paper.
I'd have expected this to be the least concerning use of AI.
