oh and, v-lang does have GC. they use boehm gc.
> They should have reached 1.0 by now...
These are strange statements. People having any familiarity with newer programming languages are likely to not know or be confused by where this is coming from.
V is a relatively new language that came out in 2019 and is in beta. So comparatively speaking, V has progressed well at the least, debatably quite fast. V also has more GitHub stars than all the listed below languages (in beta) combined (per OSS Github language rankings). Let's look at the starting dates for these popular and newer languages:
1) Zig came out in 2016 and is still in beta.
2) Odin came out in 2016 and is still in beta.
3) Jai started in 2014 (full time around 2017) and is still in beta.
4) Red came out in 2011 and is still in beta.
The languages that we see today, which are popular and at the top of the rankings (like TIOBE) are significantly to quite old. Among the youngest languages in the top 20 (your post mentions Rust and Go), they came out in 2015 (Rust), 2014 (Swift), and 2009 (Go). All of these have huge corporate support.
No, because C was derived from B. B was created in 1969 and was much of the basis of what would become C, which is given the release date of 1972. So we can make the argument of at least around 3 years of development, of what would be named C, before reaching a stable or usable enough state.
Languages and goals were much simpler in the past. Stages of development like alpha, beta, or what was 1.0 get kind of mixed up. It's not as clear a process, as we have today.
> Except for jai, because jblow has other things todo
Surely the other language creators had/have other things going on too. One of the main differences, that was attempting to clarify in the previous post, is that certain programming languages have huge corporate backing, which affects their development time. C (AT&T), Go (Google), Rust (Mozilla), and Swift (Apple) have reached 1.0 or stability faster, because of who they have supporting and pushing them.
Independent and more grassroots projects can sometimes achieve 1.0 in comparable times. But, this seems related to how exceptionally talented the lead developers are, experienced (as created other languages before), goals of the project (simpler is often easier), popularity, or how many contributors and sponsors got involved.
Crystal, looks to have took around 7 years to reach 1.0 (though with Windows support issues). Julia, comes in at about 9 years. Nim, another notable project, appears to have took around 11 years. We might can expect things to go a bit faster now, than back then, but within reason. And referring to programming languages that are reasonably well known and used.
