If you write it in all caps, that doesn't make it an insane idea. SpaceX didn't invent VTVL. The first successful examples date to the Apollo program, and you have the McDonnell Douglas DX-XA in the 1990s. Falcon heavy worked because the idea wasn't a retarded idea. A heat shield made of unobtanium, by contrast, is a retarded idea. And the fact remains that Starship is 5-10 years behind schedule, the unobtanium hasn't been invented yet, and SLS has already done a flyby of the moon. Starship was supposed to do a manned flyby of the moon in 2023. Musk even sold tickets for it!
You really think Amazon and Microsoft have never hired engineers to develop new technology? You know, one difference between Bezos and Musk is that
Bezos's high-performance microchip actually made it to production. Dojo remains vaporware, as anyone who knows anything about the business predicted the day it was announced.
