I use neither Go nor Rust and don’t have an opinion, but it’s worth pointing out that “difficult to learn” is highly contextual, e.g. Python or Ruby were probably relatively easy to learn if you already knew Perl or PHP. I found Haskell quite difficult to learn. Subsequently PureScript was very easy. Widely shared knowledge and concepts change over time and they will affect ease of adoption.
