Have you ever tried to pick up a pen in your life, pal?
I have, but it wasn't enjoyable for me.
I'm creating this visual novel while having a full-day job, often working on it for several hours after the work. This is only sustainable if the thing I'm doing is actually fun and enjoyable for me. Drawing just isn't that fun for me that I can bring myself to do it after work consistently. On the other hand, stable diffusion (i.e., the AI tool I've been using) has been very fun for me, which is why I was able to stick with it for a longer period of time.
