I don't think you quite get the engineering challenges of building a hypersonic aircraft.

It's not just a case of slapping bigger engines on. The demand for a passenger scramjet isn't high enough to offset development and maintenance costs.

For moving large payloads, we're not moving away from turbofan any time soon.

Some people just really struggle to separate business from personal feelings, and understand the complex nature of having an investment board or large groups running things. While it's nice they did this, it should be obvious that many other changes will eventually follow that will be a net negative for the content and users unfortunately. Always is when this happens. It's good the subreddits are gone, but bad if overall users drop like a rock or leave in droves because of profitable changes.

The prototype was a large sized drone powered by a conventional aviation fuel powered turbojet at speeds of about 200 km/h. The switch to hydrogen is theoretical, the hyperspeed (let alone supersonic) is just aspirational. And by aspirational I mean

  1. Raise lots of grants and venture capital
  2. Keep lots of scientists, engineers and management paid for many years
  3. Give up in about 10 years and move on to new project
