We all stand on the shoulders of giants. Yes, I want artists and other creators to be compensated fairly for any work that they contribute into training datasets, but outside of that there is no moral responsibility AI creators should feel towards those whose potential careers would be impacted.
They aren't. Every person is free to use AI or not.
Go blame your fellow consumers if you don't like the fact that they prefer AI.
These are choices that everyone makes. AI companies alone aren't forcing everyone to use their cool new tools. Instead, thats a decision that 10s of millions of people are making every day.
