You will never be an A320neo. You have no ground clearance, you have no support for ULDs, you have no ability to land in a way that would not wipe out the dinosaurs. You are a 60 year old airframe twisted by fuselage extensions and ♥♥♥♥♥♥ MCAS software into a crude mockery of old Boeing's perfection.
All the "validation" you get is two-faced and half-hearted. Behind your back people mock you. Your airlines are disgusted and ashamed of you, your "pilots" laugh at your ghoulish appearance behind closed doors. Passengers are utterly repulsed by you. Thousands of hours of flying have allowed passengers to sniff out frauds with incredible efficiency. Even 737s MAX who haven't crashed yet look uncanny and unnatural to a passenger. Your hamster pouch engines are a dead giveaway. And even if you manage to get an inexperienced flyer to board you, he'll turn tail and bolt the second he has to sit in your narrow seats.
You will never be trusted. Your pilots wrench out a fake smile every single morning and tell themselves it's going to be ok, but deep inside they feel the dread creeping up like a weed, ready to crush their spines under the unbearable force of the landing.
Eventually it'll be too much to bear - your single AOA sensor will give a bad reading, MCAS will kick in, you will enter an uncontrolled dive, and plunge into the cold abyss. The FAA will find you, heartbroken but relieved that they no longer have to live with the unbearable shame and disappointment. They'll bury any notion that MCAS is to blame, and every passerby for the rest of eternity will know a Boeing 737 crashed there. Your engines will decay and go back to the dust, and all that will remain of your legacy is a fuselage that is unmistakably 737. This is your fate. This is what Boeing and those ♥♥♥♥♥♥♥ at Southwest chose. There is no turning back.
