It might be possible in the future to have commercial aircrafts with an airframe changing depending of the flight regime. See https://m.phys.org/news/2019-04-mit-nasa-kind-airplane-wing....

Well, they do. That's what flaps are. They change the shape of the wing to better optimize for slow flight. Swing-wings work but are hideously heavy/expensive. We will never see an airframe able to morph into constantly ideal shapes like a birds do.
