Your article is good and more focused on granular approach in public markets and instruments. Thank you for sharing.

I have pondered this as well. I see a lot of discretionary traders on Instagram and a lot of them I suspect are faking it and don't have an edge but are just selling courses.

I wonder how (not AGI) just more developed AI that creates changes in public markets - as you said new instruments, new strategies, would change their edge.

As it is, discretionary retail traders simply don't have access to the same data and tooling for active day trading as do professionals.

Things are about to get very interesting.
