This is a tautology, no? There's plenty of great art being made today by people feeling the same emotions as those in the past.

Modern art and artists indeed do mirror the feeling of their age.
No one is stopping you from commissioning paintings such as the ones you revere as the peak of art, by the way. Open your wallet if that's what you want. That's how great art was made back then. But if the depth of your insight on the human condition is whatever you're posting here, I do not know if your commissions would capture the meaning you seem to want.
We can make better than the past for sure, there is no point to rehash the glory of old, but we so far have not. In archeology there is a constant and agreed upon "decadent" style that can indicate when cultures have experienced conditions, for external or internal reasons, that ultimately led to their decline and downfall.
It's amazing that we cannot recognize the same precursors in our own. But perhaps this is interdisciplinary blindness?
Actually, re-reading your original post, this comes across as so asinine I do have to wonder if I'm replying to an LLM. Because it makes no sense to say that artists don't have emotions today that can compare to checks notes rowdy Venetians beating the shit out of each other.
