No, I'll believe you. I used to work as an artist during covid for a vfx studio. Previously I had done some freelance illustration and other very specialized craft work I'm not going to talk about because it's very niche, and I'll doxx myself.
Anyway, for a variety of reasons beyond my control all that ended, I got depression, unemployed, and while I was trying to get back on my feet we got this fucking AI explosion. All my work posted online has to have been used for training models. And I haven't posted anything online since- in fact I haven't found the motivation to complete a single artwork at the same level I used to. I've been dedicated to learning more technical things in vfx, but failed to get an industry job for over two years now. I got a couple basic customer service jobs for the first time in my life, which I'm not enjoying much and really don't give me an opportunity to use my skills, knowledge or talents in any way, but they give a paycheck so whatever.
While AI isn't the original reason for my unemployment, it really influences my job prospects now (negatively). It has also absolutely ruined what used to be my online network and online art community, which was essential in keeping my mind in the right place. I'm not personally aware of any artists that have committed "passage to another world" (as you say- is this because of word filters?) because of this, but as I've explained I've withdrawn from my previous circles so I wouldn't be surprised artists getting triggered into self harm because of AI. We artists tend to be more sensitive and react more strongly than other people under certain circumstances.
AI and all its consequences really weigh heavily against my mental health - it discourages true artistic expression, which in turn exacerbates isolation and a feeling of pointlessness. Yes it's absolutely a reason people would want to un alive themselves.
