Salute!
Not so sure the Max will survive, and even with more and low-priced NG variants, folks will still be leery of buying the planes as long as it has "737" in the model number.
Back in the day Lockheed bit the bullet on the Electra and did major hardware/aero fixes. The result wound up as the P-3 ASW platform and served for over 4 decades, and even now being replaced by P-8's. However, public trust had been lost and Lockheed walked away from the commercial market and sold P-3 planes to all comers.
The looming, myriad of trials has yet to begin, and their publicity will not impress folks that discover their ride to visit grandma is one of the "fixed" Max platforms.
Only way Boeing can survive is to stop selling the MAX with MCAS. Fix the aero problem and advertise "no MCAS required", or simply stop selling the model and take the $$$ hits.
Gums opines...
