Fuck the creative process, the journey it takes you on, and the necessary introspection and connection to the world that needs to occur for it. Fuck the joy you can find in effort, failure, and in finally having an epiphany. Fuck being able to hone your skills without depending on a corporate tool that can be taken away from you at a minute’s notice. All of it be damned, you can now (allegedly) get to the same end result quicker without the effort (or pleasure, or self-discovery, or personal growth). We all know that the end result is what counts, and nothing else.
Is anyone claiming you can't do that? The use case for most AI slop is soulless corporate graphic design that's about as worker bee as it gets and the rest is mostly people using it in place of hiring an actual artist for their weirdly specific niche pornography. And the guy wanting you to draw him something involving dolphins with a foot fetish isn't deeply concerned what your personal journey regarding the nature of creatures without feet who are obsessed with them sexually looks like.
At it's heart, the non-environmentalist AI hate is mostly people who thought their jobs were impossible to automate trying to protect those jobs from being automated.
