Agreed. His ELO improvement alone is evidence enough imo.

His rating plateaued around 2300 from end of 2015 to mid 2018. Then in the last 2 years, I believe his improvement from 2400 to 2700 is the most rapid in history.

If you compare his rating with other young players like Duda, Firouzja, Gukesh - then his rating increase looks very unique.

I'm not aware of any chess prodigies that have followed a trajectory quite like this. So maybe Hans is an unusual talent. Or maybe, he's receiving computer assistance.
