Here's a wild guess: Through SpaceX design experience (rip apart, challenge all assumptions and rebuild better), Elon Musk (Falcon Aviation) will try to build a far more efficient and safe alternative to existing 737s.

Falcon Aviation got hold of various aircraft, which I think they'll just reverse-engineer and throw out what's not working. It's like taking pretrained weights from an established LLM: https://www.businessinsider.com/elon-musks-spacex-bought-a-b...

With Trump coming to power, Boeing's tarnished credibility will be a major issue to address. I'm expecting US government will incentivize this process. Boeing will lose good engineers out to this fresh competition.
