For comparison of some other currently popular languages (above it on the Tiobe Index), time from 1.0 (or something similar where typical modern versioning isn't applicable) is: Python 27 years, JavaScript 24 years, C 43 years (from K&R, realistically might count 1.0 earlier), C++ 36 years, Java 25 years, C# 19 years, Ruby 19 years, VB.Net 20 years, classic VB 30 years, Groovy 14 years.
Go is a relatively new language. Not quite as young as Rust, but young for an industrially-popular language.
It’s been 12 years next month. Might be time to change that?
