You can't draw sprites without electricity!!! :( wacom should work :) I completely agree that someone should supervise the creations created by the AI. By the way, there are many people who do not have manual dexterity but have amazing senses. If it is an AI brush that is much easier to handle than a brush, wouldn't it be possible for non-artists to supervise it?
Viewing post in Do you think AI can replace game artists?
You can draw sprites without electricity but with pen or pencil on paper :D.
As for supervision, it really depend on desired quality of the product. If the dev is happy with low quality artwork from the AI, it's fine for them. Maybe it's their intention and probably they don't need professional artist in the first place.
However, if the dev wants high quality artwork, professional artist might be needed to supervise the art creation by AI.
I watched in a youtube video that this AI requires more electric power and that's the downside of AI.
