I wonder what you consider a successful language.

Rust appeared in 2012. Zig in 2016. I consider them both two successful programming languages, but given they are only 4 years apart, it's easy to compare Zig today with 4-years-back Rust and see they are very far apart, in term of maturity, progress, community size and adoption.

Rust is a very successful language so far, but expecting that in 10y it can overthrow C++ is silly. Codebases add up more than they are replaced.
