that's what the comment means we as people went from picking Ada to ReactJS
of course we also went from having no Rust and no TypeScript and only a few hundred thousand semi-academic people having some knowledge of programming to hundreds of millions of people doing some tutorial/bootcamp/cert/degree, or even built something, or actively learns, or right now works as a professional programmer.
(un)fortunately Ada was not able to grow to became the default tool for all these jobs that all those millions of people did or wanted to do when they did/do programming.
JS/ECMAScript is evolving, things are getting better!
