Someone in the Go team (rsc, IIRC) commented on how a Google executive came to him in the cafeteria to congratulate him on the launch. It turns out the executive confused him with someone on the Dart or Flutter teams.
Now a bit of personal history. The Go project was started, by Rob,
Robert, and Ken, as a bottom-up project. I joined the project some 9
months later, on my own initiative, against my manager's preference.
There was no mandate or suggestion from Google management or
executives that Google should develop a programming language. For
many years, including well after the open source release, I doubt any
Google executives had more than a vague awareness of the existence of
Go (I recall a time when Google's SVP of Engineering saw some of us in
the cafeteria and congratulated us on a release; this was surprising
since we hadn't released anything recently, and it soon came up that
he thought we were working on the Dart language, not the Go language.)
