I've worked with some of the top designers in the world. I don't think that AI will beat them (for now), but the examples in his sample page[0] beat the junk that I've seen a lot of non-top-designers do.

As he states, he isn't trying to make stuff that doesn't "look like AI did it," he just wants to introduce variety, and has proposed a disciplined way to do that.

can you please list some of the people you worked with? I really appreciate good design and am always looking for great artists that I don’t know about yet, thanks.
