I think the issue is that it's hard to trust the language to go over its current limitations without commercial backing. This is especially true for a language like Go which had limited functionality and a complete lack of tooling (eg. no package manager, no generics) for a long time. I didn't pick up Rust until a few killer projects were released. Before that async was a complete mess. For a long time we didn't have the ? operator.
