Eh, I figured I would get this response but writing software e.g. your IBM, Yahoo, and Microsoft example is much easier and faster to do than building a cutting edge, physical, supersonic commercial jet. To build Google, all you needed was a computer, and a new approach/algorithm to solving web search. Software companies are much easier to disrupt than physical product companies.

As others have pointed out the Tesla isn't a great example either because building a car is still 100x easier to do than building aircraft, let alone supersonic planes.

"Unexpected Insights" and "A new research breakthrough from some other field" seems to be handy wavy. A supersonic jet breakthrough is not something that can be discovered in a dorm room. It requires millions in research and expensive materials to build and test against.

I did include SpaceX as well, and I'm not sure one can find a better example than that, but there are others as well:

- Cruise + other self driving car companies (obv also a bunch of software, maybe even software focused, but looking at Waymo, they developed all their own hardware, LIDAR tech etc.)

- Commonwealth Fusion + a bunch of other fusion startups (obv they haven't really gotten to a product yet one could argue, but a bunch of breakthroughs in high powered electro-magnets has been made)

- Heart aerospace - electric planes

- Canvas construction - robotic plastering and painting for construction.

While supersonic flight has been proven, albeit not economically viable, it's still something that has been done, and done like 40+ years ago. It's not really on the "fusion power"-levels of difficult. But sure, I guess on could argue both sides equally well :)

In regards to research breakthrough, sure they were handwavy at least as it relates to jet engines capable to support supersonic flights. I don't have any sources but I have little doubt that jet engine / material breakthroughs has been made since the 80:s.

SpaceX, yes. But I think some of these other examples work against your point. Yes, some of them have raised lots of money (or even sold for lots of money), but revenue for Cruise + Commonwealth Fusion + Heart combined (I haven't heard of Canvas) is about $0 so far. It's yet to be seen if any are viable businesses even if they have already invented cool shit. To your point above, Boeing is not in the venture capital business. Their investors most likely want dividends and stock buybacks, not capital intensive moonshot bets.
