Three programming languages - Julia, Nim, and Crystal - reached the all-important version 1 milestone in the last 5 years. That feels like a substantial achievement. What impact have these languages had on the industry? Small impact so far but it is early days. Anecdotal observation: Julia seems to be gaining greater traction that Nim and Crystal. However, although Julia is a general-purpose programming language, the close association with scientific computing may see it pigeonholed by some developers as suitable only for that domain. It's refreshing that all three languages count performance as a key feature. Together with Rust and Go, this has had some impact in making developers aware of the importance of performance in programming, and the advantage these languages have over less-performant languages.
