If only they had waited and invested in designing a whole new commercial aircraft.

...

Do you have any idea how much money that costs and how much time it takes, not just for Boeing, but the airlines, too?

You don’t seem to have a problem with Airbus modifying their A321 to save money and time.

Yes but the return on investment in a new, innovative plane would have been well worth the wait! Now look where they’re at and all they stand to lose! Regarding Airbus A321 - from my understanding, the foundational structure does not present the same aerodynamic/gravitational challenges as the Boeing 737 — when it comes to things like placement of the new engine on the plane, how far high it is off the ground, etc...

I just posted US Army’s frustration with Boeing among others:

I don't know about aircraft, but in something just as complex, microprocessors, some designs lend themselves to redesign and scale better than others.

Back in the 1980s, the Motorola 68020 series was a better architecture than the "brain-damaged" 80286 from Intel. The old Mac II series used those chips. Unfortunately for Motorola, the 68020/68030 technology did not scale well and was running out of juice with the 68040 series, and Apple and company had to change over to the PowerPC series which was radically different, while Intel moved seamlessly along, patching and extending the 80286 into the 80386, 80486, Pentium etc.
