At this point, there are two kinds of successful artists.
Those that tell you that they use AI to assist with their craft, and those that lie about it.
Because the amount of extra work that needs to be done to without AI is ridiculous at this point. Add to this the part where AI provides several unique services that humans cannot deliver in time frames that aren't thousands to tens of thousands of times longer, allowing for rapid iteration on concepts that would be impossible otherwise, and today you no longer can be successful without it.
The only difference today is how much of it is used, for what parts, and what specific model.
