"The key point here is our programmers...
They’re not capable of understanding a brilliant language...
So, the language that we give them has to be easy for them to understand"
Yep, if Google wasn't behind Go the language would have already been history like so many other half baked technologies. It won't be long untill people will talk about Golang like they do about JavaScript.
They said the same thing about JavaScript in the 90's. If Netscape wasn't behind it... Over 25 years later, it's still going strong, even though the entire HTML/CSS/JS model of "app development" is and always was half baked.
Honestly, I expect Go to be lumped together with JavaScript in terms of "weird but still in use" languages in the long run.
There are so many surprising footguns and unsafe patterns that it really stands out as a risky language to me. But it has Google's (implied) backing and it works well enough to be used, and the performance is very good in general.
By this point it can probably survive for quite a long time on momentum alone. Which makes it a moderately-safe-to-use-in-a-business language.
