Time will tell.He was F2 Champion before moving to Haas. I think he's just been at the wrong team. Remember Haas chose not to develop the 2021 car in preparation for the 2022 seasons new rules which handicapped him badly. He's been partnered by Magnusson this season who has had an incredible rise after a sebatical in 2021.
I agree he isn't his Dad but there is a racer in there, one that I think could be a useful tool to the top teams. I'm glad Merc signed him up as the Test Driver for next season.
Maybe Haas wasn't the right fit, but in F1 the only benchmark you have is your teammate. He was consistently slower.
