The Lunduke effect.

Mozilla, where Rust was originally conceived, have already talked about this risk factor ages ago when they were still working on Servo. Reimplementing battle-tested software in a different language can result in logic bugs being introduced, which no programming language can really prevent. Many times they will actually reintroduce bugs that have already been historically fixed in the original implementation. This doesn’t invalidate the benefits of moving to a very memory safe language, it just needs to be taken into consideration when determining whether it’s worth the risk or the effort.

Honestly I have no idea whether sudo-rs is a good idea or not, but I have my doubts that any of the other people (especially the very vocal kind) chiming in on this do. Any time Rust is involved in the Linux community, a lot of vocal critics with very little knowledge of the language or programming in general seem to appear.

I think you’re just being contrarian for no reason. The market for specialty input devices is much smaller compared to “normal” keyboards but it still exists and has become much more diverse over the past decade, with many new niche products being launched. This isn’t even the first commercially available chorded keyboard. From the video, this particular iteration seems to be marketed towards mute people and I’m sure that they or people with other kinds of disabilities are probably glad to have any products at all available to aid them in daily tasks. Not every product or company needs to participate in a high volume market. Apparently, the chorded inputs can also be reprogrammed and it can work in a normal keyboard mode, which should make it more flexible than something designed purely for stenography.
