How would you respond to William Rowe argument against St. Thomas Aquinas argument from motion?

Philosopher of religion William Rowe, who has been a long standing critique of God and Christianity put out an argument against St. Thomas Aquantius argument from motion, by arguing that things such as quantum mechanics show that there doesn't need to be a chain of motions, how would you respond?

"The claim that there must be a first mover is questionable, given that quantum mechanics and modern physics suggest that events can occur without deterministic causality, making the necessity of a first cause less compelling."
