I think Go is quietly taking over some business domain applications, reminiscent of Python ca. 2003 a lot of companies I see are using it for a few key components that benefit heavily from memory savings of value types and/or easier naive concurrency, but they're relatively quiet about it. There's also a small but significant cohort of junior devs today who learned to program by making games on fantasy consoles or homebrew hardware projects, want to keep working with those data-oriented patterns they learned C and C++, and Go supports that style a lot more idiomatically than Java. As much as I sometimes rant about "kids today", more of the current generation know the true value of a MB or a ms better than that of 10 years ago (Rust is helping a lot here, too).
