I want to ask and answer two of my own questions here:
1. Why clone Jeff's voice?
When I was messing with stable diffusion using Automatic1111's interface, I noticed it came with a big list of artists to add to the prompt to stylize the image in some way. There was a big row in the media about ai art reproducing artists work and many artists came forward feeling it was a personal attack. But... I mean the truth is more general than that. When I pressed a button to insert a random name into a prompt, my goal was not "yes give me this person's art for free", it was "style this somehow".
I wasn't personally interested in any particular artist, I honestly would have preferred a bunch of sliders.
Jeff here is clearly a good speaker. That's a practiced talent and voice actors exist because it's hard. Elecrow wanted a voice over and they wanted it to be as good as they could make it. Jeff is very good. So did they want Jeff?
I think what they really wanted was a good and cogent narration with the tenor of a person. Not a machine making noises that sound like english. If they had an easy way to get that, we wouldn't be talking about it here.
2. What function does copyright serve?
Well. I think a reasonable argument would be that if people were able to reproduce your work for free, you would quickly find yourself without a monetary incentive to make more of it.
So. What happens if you combine answer 1 with answer 2?
I think it leads to: "We should consider making it illegal to automatically reproduce the work of an artisan.", you know, the luddic argument. An argument that has been perceived to be, more or less, settled.
So it seems to me: That for individuals, harms matter, and for society, it doesn't.
