I understand both sides tbh...
Like, sure people some artists will feel like their actual talent is being infringed, and in cases of those idiots calling themselves "AI Artists", I agree.
But also, I got an already existing picture of me and my fiancΓ© in a different art style and we both looked cute, also did the picture of my cat. If I wanted a personalized quality cartoon of ourselves it would've cost me at least $150, so for a fun, already existing pic of ourselves I'm ok with it,specially if it's to keep to myself or maybe posting in a "hey check this out lol" way, I'm not saying I'm an artist or claiming is original content.
If I wanted a REALLY special picture made to my specifications by an actual artist, of course it would be worth it since I'd ask them to do a "custom" scene and such (that's the creativity part IMO), but just "translating" an already existing picture, I think is ok as long as you don't claim you're the artist or try and get credit for it either.
