> Instant boot time. Because rust is statically compiled, there's no runtime startup or anything involved with it. From dead to alive is pretty much instant. Dynamic linkage is not the slow part of application startup. The slow part (for applications which are slow) is almost always the gathering of non-compiled assets from disk. IMO, the lack of dynamic linkage is Rust's #2 weak point, second only to slow build time…

You can use dynamic linking with Rust. You just have to stick to the C ABI when interfacing w/ shared objects, because there is no stable Rust-specific ABI.

> a bunch of FAANG driven contributions tend to make projects focused too much on particular use cases This is one of the challenges we have, as a project, in this next phase of its life: make sure that we are helping organizations achieve their goals, while not allowing it to be totally directed by them. Rust governance is set up to be resilient to takeovers by any one organization, but we're now playing with some o…

From my perspective, the size of the companies has little to do with the relative risk of outcomes that are not the best for the common good. I've seen folks at small companies try to control or unduly influence open-source software, and I've seen folks that work at large companies do it too. At the end of the day, I think it comes down to the actions of people directly involved in a community, and the culture that t…

(!) I was under the impression that you could not develop a shared library in Rust even if you exposed a C ABI.

> Rust is a developer’s delight and I don’t want it to become like C++, and I feel the C++ standard got worse especially after these so-called great companies became a part of the standards committee. On the Rust language team, we are extremely mindful of managing complexity, and we typically err on the side of not including a feature (even if it's desired) if it feels like it adds too much complexity or surface area…

The biggest problem here, though, is that look at Google in web standards: the web is now what Google say it is, IE 6 style. If Googlers don't get their way with the Rust language team, they'll just attack the language team head-on, or bypass them. Google have zero interest in collaboration.

Java is nowhere close losing the #1/2 spot in programming language, it's just everywhere.

I agree that Java is not going anywhere, but I could absolutely see a world where JavaScript and Python are number one and two.
