Philosophical masturbation, based on a poor understanding of what is an already solved issue.
We know for a fact that a machine learning model does not even know what a rosebush is. It only knows the colours of pixels that usually go into a photo of one. And even then, it doesn’t even know the colours - only the bit values that correspond to them.
That is it.
Opinions and beauty are not vague, and nor are free will and trying, especially in this context. You only wish them to be for your argument.
An opinion is a value judgment. AIs don’t have values, and we have to deliberately restrict them to stop actual chaos happening.
Beauty is, for our purposes, something that the individual finds worthy of viewing and creating. Only people can find things beautiful. Machine learning algrorithms are only databases with complex retrieval systems.
Free will is also quite obvious in context: being able to do something of your own volition. AIs need exact instructions to get anything done. They can’t make decisions beyond what you tell them to do.
Trying? I didn’t even define this as human specific
