Wait, wait, you can use C everywhere, and absolute lines of code is the metric people seem to move away from C as quickly as possible to higher level languages that perhaps aren't as portable (Python, Java, C#).

Re: embedded, this is just terribly short sighted. Right now, yes, C obviously has the broadest possible support.

The issue is that C has no adoption curve. It only has ground to lose. Meanwhile Rust is, relatively, a delight to use, and offers important benefits. As I said elsewhere: "Unless I am wrong, there is still lots of COBOL we wish wasn't COBOL? And that reality doesn't sound like a celebration of COBOL?" The future looks bright for Rust, if you believe as I do, we will begin to demand much more from our embedded parts.

Now, will Rust ever dominate? Will it be used absolutely everywhere? Perhaps not. Does that matter? Not AFAIAC. Winning by my lights is -- using this nice thing rather than this not so nice thing. It's doing interesting things where one couldn't previously. It's a few more delighted developers.

I'd much rather people were delighted/excited about a tech/a language/a business/a vibrant community, than, whatever it is, simply persisted. Because "simply persisted", like your comment above, is only a measure of where we are right now.

One way to think of this is -- Perl is also everywhere. Shipped with every Linux distro and MacOS, probably to be found somewhere deep inside Windows too. Now, is Perl, right now, a healthy community or does it simply persist? Is its persistence a source of happiness or dread?
