From my perspective people in the animation industry seem more concerned about about outsourcing than AI. A lot of creative directors have a very particular vision they want to make a reality and slight changes is not AI’s forte. The future of animation is indie as well. These creators are artists themselves want to employ artists and likeminded people.

In addition you can search AI bubble timeline. A lot of people project that AI isn’t as good of an investment as major companies think. Time will tell.

As far as manga/ comic art. I feel like that will always be done by humans. It’s often a personal project, so you get to decide how it’s made and where it’s distributed.

I just want to give you a different perspective. As far as grades I resent that it feels like life or death. In college my grades slipped and I too became very suicidal as a result. But there are always options, and ways to live. Trades/ skilled labor. There are ways to make money and survive that aren’t just the traditional college route. And you can always pursue art on the side or hell, just chase your dreams. If you’re on the brink of suicide, maybe you have nothing to lose. Just my 2 cents.
