I don't mind the idea of them using AI....but, and I would say this of any artist, only if it allows them to do more, if it becomes a method to do the least amount of work, then is a load of shite.
Surely Sunsetrider must enjoy drawing, he is very talented, I hope this gives him the sparkle to dedicate himself to the better parts of the job.
The way I see it, AI art can be like taking a great sculptor and having some assistants do the rough parts of the sculpture then he/she comes and put his/her own touch in the details.
