Most and least future-proof languages for hobbyists and users?
As a hobbyist/computer user who views programming as a tool to make life more convenient and productive, what are the languages that will allow me to write code once and not worry about frequent updates to the code?
Because I don't want to pursue programming as a profession I don't think I can keep up with all new language updates and it would be nice to have something in my toolkit that I can learn once and apply over time.
Conversely, what are the languages and technologies that have a lot of updates and you have to stay in the loop and keep learning to keep your apps functional? Just so that I know what to avoid.
Context: I want to make personal apps for Android and desktop but not through web technologies. But I'm interested in other domains as well so if your comment doesn't cover Android or desktop I'll be interested anyway.
