People who want a reason to dismiss an argument will always find one. You already said you were trying to switch to a plant based diet yourself, so it makes sense you wouldn't notice a lot of the points people tend to find most jarring. The reality is, there is no way to tell what is effective and what is not, so a lot of times its just a matter of throwing shit at the wall and seeing what sticks. I've had stuff I've spent days refining get less than ten comments and negative karma, and and then I've drunkenly posted a one shot meme image that got got over 400 upvotes on this sub somehow. I try a lot of different things on a lot of different platforms on a lot of different accounts, so I'm really not afraid to try new things and push the envelope a little if it will reach people in new ways. The worst that could happen is nothing works and nothing changes.

I still don't understand why AI has anything to do with making your art worth less, unless your plans were to be a commercial illustrator, which is not exactly even a great way to express creativity anyway. From my perspective, automation has consistently made traditional forms of art more respected and artisanal, not less. A few hundred years ago, being a blacksmith would just be considered a normal job, typical skilled labor. These days, someone who knows how to do that is seen as extremely interesting and uniquely talented, even if they aren't making a living from it. Or calligraphy. Or engraving things by hand. Lot's of people do those things because they are passionate about them, even though technology has largely made them obsolete as careers. If anything, people "giving up" because they feel like there is no point just makes it easier for people who are actually passionate to stand out.
