I'm not sure where this perspective comes from. Rust is growing extremely quickly, far outside the HN bubble. Rust is used by, and financially supported by, many of the learning companies in the technology industry: Microsoft, Google, Facebook, AWS, Dropbox, and others. It's being piloted for use in the Linux kernel and is already accepted into Android. Unlike Ada, its development was never bootstrapped by public funds and so all of its growth is due to its practical benefits. I don't know why fighter planes are the standard to reach, but Rust is even being used in aerospace: both Rocketlab and SpaceX have made public statements supporting Rust or are hiring people with Rust expertise.

Rust usage is growing pretty quickly, a lot like C++ at its age. "Extremely" is a meaningless term in this context. "Used by <Big Company>" means much, much less than most people who mention it believe. The bigger the company, the more likely it is that they use literally anything at all you can think of, and the correspondingly less it means that they do. They might even be using it in a certain project deemed strategic. But we all know how many of even "strategic" projects at big companies end up canceled, even when they seemed to be a success. You can be certain that they are not using it for anything central to how the company makes its money. It is more interesting when a $company uses $newtech where it will only have an income if the project succeeds. But you probably never heard of $company, otherwise, so have no way to evaluate how important it is. SpaceX has said publicly it uses C++ for mission-critical work. Like other $billions companies, they do a lot of things. Saying they do Rust, too, makes them seem edgy in circles where people are likely to hear about it, regardless of how much they actually depend on it. So it is really hard to tell.

  Absolutely valid points. I'm definitely inside the filter bubble wrt Rust. It will be fascinating to see where things will be by 2030.
