Fundamentally I think this comes down to answering the question of "why are you creating this?".

There are many valid answers.

Maybe you want to create it to tell a story, and you have an overflowing list of stories you're desperate to tell. The animation may be a means to an end, and tools that help you get there sooner mean telling more stories.

Maybe you're pretty good at making things people like and you're in it for the money. That's fine, there are worse ways to provide for your family than making things people enjoy but aren't a deep thing for you.

Maybe you're in it because you love the act of creating it. Selling it is almost incidental, and the joy you get from it comes down to spending huge amounts of time obsessing over tiny details. If you had a source of income and nobody ever saw your creations, you'd still be there making them.

These are all valid in my mind, and suggest different reasons to use or not to use tools. Same as many walks of life.

I'd get the weeds gone in my front lawn quickly if I paid someone to do it, but I quite enjoy pottering around on a sunny day pulling them up and looking back at the end to see what I've achieved. I bake worse bread than I could buy, and could buy more and better bread I'm sure if I used the time to do contracting instead. But I enjoy it.

On the other hand, there are things I just want done and so use tools or get others to do it for me.

One positive view of AI tools is that it widens the group of people who are able to achieve a particular quality, so it opens up the door for people who want to tell the story or build the app or whatever.

A negative side is the economics where it may be beneficial to have a worse result just because it's so much cheaper.
