I wouldn't say its convenient, getting an AI to produce what you see in your head, its a difficult task, far harder than coding. I suppose after years of using AI and you've become used to its quirks, it could then be classes as convenient, but right now, its frustrating and difficult. I can see jobs appearing which involve just getting AI to produce content that is reasonable.
I would prefer human art simply down to the fact that a human can understand what I'm asking for, but humans cost a lot of money which I don't have. So its AI or nothing until that lottery win comes along.
