Linus Torvalds On Community, Rust and Linux's Longevity

An anonymous reader writes: This week saw the annual check-in with Linux creator Linus Torvalds at the Open Source Summit North America, this year held in Seattle (as well as virtually). Torvalds took the stage for the event's traditional half-hour of questions from Dirk Hohndel, an early Linux contributor (now also the chief open source officer and vice president at VMware) in an afternoon keynote session.... And the theme of community seemed to keep coming up — notably about what that community has ultimately taught Linus Torvalds. (For example, while Torvalds said he'd originally planned on naming the operating system Freax, "I am eternally grateful for two other people for having more taste than I did.") But even then Linux was a project that "I probably would've left behind," Torvalds remembered, "if it was only up to me." Torvalds credits the larger community for its interest (and patches) "that just kept the motivation going. And here we are 30 years later, and it's still what keeps the motivation going. Because as far as I'm concerned, it's been done for 29 of those 30 years, and every single feature ever since has been about things that other people needed or wanted or were interested in." Torvalds also says "I'm very proud of the fact that there's actually a fair number of people still involved with the kernel that came in in 1991 — I mean, literally 30 years ago.... I think that's a testament to how good the community, on the whole, has been, and how much fun it's been." And Torvalds says you can see that sense of fun in discussions about writing some Linux kernel modules using Rust. "From a technical angle, does that make sense?" Torvalds asked. "Who knows. That's not the point. The point is for a project to stay interesting — and to stay fun — you have to play with it.... "Probably next year, we'll start seeing some first intrepid modules being written in Rust, and maybe being integrated in the mainline kernel." "I really love C," Torvalds said at one point. "I think C is a great language, and C is, to me, is really a way to control the hardware at a fairly low level..." Yet Torvalds also saw Hohndel's analogy that it can be like juggling chainsaws. As a long-time watcher of C, Torvalds knows that C's subtle type interactions "are not always logical" and "are pitfalls for pretty much anybody. And they're easy to overlook, and in the kernel that's not always a good thing." Torvalds called Rust "the first language I saw which looked like this might actually be a solution"
