It’s a good aspiration to eliminate needless complexity from a language so people can spend their cognitive resources (be they great or few) on solving real problems. If you can lower the barrier such that a layman can do it, then a genius specialist can do that much more.

The problems don't go away. If the language refuses to handle them and refuses extensibility, every end user now needs to handle those problems without standard tools.

This hasn’t been my experience. I’ve been involved in the language and community for nearly a decade and I’ve never seen an incident where the grievances against the language weren’t seriously overblown. The most credible one has been dependency management. There’s still plenty of room for improvement of course, but the idea that Go’s flaws make it anything short of one of the most productive languages is generally nonsense.

Also, go is an elitist language as well, in its own way. Its creators and many of the first proponets were big Unix/C/Bell Labs names. Quite opinionated people.
