They won't do supersonic jets in particular, but they already have a ton of moonshots to try make sustainable aviation possible and with economics that make sense. Stuff like hydrogen propulsion, hydrogen electric, and battery electric designs, with a variety of weird shapes and forms. They're the only big aircraft manufacturer with such a wide array of potentially groundbreaking (if they make it) research. And theirs is drastically more important than Boom - time and time again, it has been proven that mass aviation is all about economics, not speed. Soon it will be economics + sustainability, speed being a niche which might not even be profitable (Concorde, Convair and many others have tried differentiating themselves on speed and failed).
