While I think Boeing was grossly negligent, and is in a world of hurt, there is no way the MAX program goes away. They will do a fix, make the electronic fix for the fact this plane is a dog have more redundancy and give adequate training on what happens when the MCAS system faults out.... The reality is that lots of current 737 users wanted an A/C that they can fly w/o retraining pilots/doing maintenance on two types, and that is the primary (or only) benefit of the MAX. Lots of folks will buy it for fleet commonality (think SWA, easy jet).

I do think this will hurt around the edges, especially if the FAA or some foreign agency requires a different type rating on the plane or simulator work on it. The main damage is reputational. Anyone who thinks Boeing is more careful, more airplane focused, at this point needs to have their heads examined.

What I do wonder about is if Airbus decides to kick Boeing while it is down, and announces a A322neo (further stretch of the A321) which would put Boeing into a really bad place. Were I Airbus I would do that ASAP, try to steal some of the MAX10 orders and the MOM space before Boeing has a chance to get off its heals.
