Will humanity have strong evidence of a moral proposition that is demonstrably stance-independently true by that time?

This would require such a moral truth to be scientifically observable and/or logically/mathematically inferrable using a standard set of axioms those fields already use in 2024.

As a moral non-realist who thinks the is/ought distinction is pretty strong, I have no idea what this would look like to resolve YES, but IMO it would be good news.

I will resolve based on my best judgement. I won't bet on this question.
