Rust is 11 years old, Go is 12 years old.

Graydon Hoare began working on the language that would become Rust in 2006. Rob Pike began working on the language that would become Go in 1995. Neither of these are useful dates because the languages that were eventually produced were drastically different at their inception compared to where they eventually ended up.

For the purpose of maturity, the point in time by which to begin measuring the age of a language is the first point at which a stable release appears for general availability. Go is 9 years old, and Rust is 6.

I think it would behoove you to explain how you're coming up with that number, given that the person you're replying to has pointed out exactly when Rust 1.0 was released.

If we're going by design inception dates, Go goes back to 2007 or earlier.

public announcements.

This is a weird metric to use, given that Rust was incubated at an open source company (Mozilla) while Go was developed for years as part of a private project. Put another way: Rust's development was much more public than Go's was; why should that be held against it?

You're feeding a troll that's managed to derail the point/conversation with an incoherent offtopic comment... I really doubt they care what you or anyone has to say to them (which is evident from their replies). Their comments/replies give you just enough material to pull you in, and then they grapple you to their level. It doesn't even have to be intentional/conscious on their part, but they're definitely doing it.

Not necessarily the troll's motivation, but: there's also a lot of "Rust envy"[1] going around from some people (mostly disgruntled C++ devs who feel threatened by it) who'll baselesly say anything and misrepresent something to prove their point. How does it never cross their mind that they're on the wrong side of things if they have to grasp for lies to prove their points?

[1]: I came up with the term just now, but I'm not sure "envy" is the right word; maybe "petty spite" is a better term.

I'm back-and-forth on whether they're actually a troll. In the best case, they're a non-L1 English speaker who's upset but isn't making particularly coherent points. But things are coming to a close anyways.

I wasn't sure if it's a language issue at first myself (I'm still not completely sure), but based on their replies it seems like it's just a fruitless smear quest because they don't like something about Rust.

Nothing about what I said implies a value judgment about Go (or even Rust, for that matter). This is now the third time this comment tree has gone into accusations of strawmanning. Have you considered that nobody's trying to strawman you, but rather that people are struggling to find coherency in your points?

Rust was announced in 2010. Many sources state it is 11 years old.

The kernel is a crucible. I'm curious to see if it's system facilities are adequate and operate with reasonable costs in that context. We'll have to see, but I am still suspicious of what often comes across as hype.
