I have received 3 transmissions from you so far, and you have yet to define "success" or "popularity", nor have you specified the threshold between "popular" and "very popular", despite having agreed with me that these things are not important for languages. Moreover, you haven't brought any figures to bear in supporting your claims. I think if we are going to continue this discussion, you have to substantiate your position -- otherwise I don't think you've said anything here that I haven't already responded to.
A specific definition of "popular" doesn't matter. What we can say is that Rust's market share at age 10 is lower than that of Fortran, COBOL, C, C++, VB, Python, JS, Java, C#, PHP, Ruby, TS, Kotlin, and Go at that age, but it's bigger than that of ML, Haskell, Erlang, and Clojure at that age. I don't know if I can compare its market share to that of Ada at that age. I'm nearly certain that much larger (and definitely more important) programs were written in Ada circa 1990 than are being written in Rust today, but it's hard for me to compare the number of programs.
