What will happen to Tony Stark?

Marvel has made it no secret that once Avenger's infinity war is released in 2019 Robert Downey Jr probably won't be playing Tony Stark anymore simply because of his age leading many to believe the character could possibly be killed off, recast, or replaced by another similar hero if so here is who I think should replace him.

Replace him with Riri Williams
Riri Williams is a new character in the Marvel comics universe who rivals the character of Tony Stark's intelligence, and charisma. She made her first appearance in May 2016 and was popular from the get go. She is first seen at M.I.T a school that Tony Stark owns stealing parts in order to make her own suit of the Iron Man armor. Tony catches on to her plan after several guards let him know one of his old armors is missing. Tony tracks the old armor down and witnesses Riri saving a child. Tony later confronts her and after witnessing her heroism gives her his blessing to become a superhero.
