The comments came during the latest episode of the firm's "Exchanges" podcast, according to a transcript provided exclusively to CNBC.
Just as people lost navigation and memorization skills with modern inventions, bankers risk losing analytical abilities if algorithms handle all the heavy lifting, Churchman said.
