I agree, but a counterpoint: Dart from Google. Despite the resources poured into Dart, it does not enjoy Go-levels of popularity. Flutter + Dart is now the focus, but it's too early to see if the language will grow in adoption.
Because it wanted to take over the Web via Dartium, then Chrome dropped support for it, it almost disbanded if it weren't for AdWords team, and Flutter gave it a 2nd life.
