The standard library is robust... The language itself isnt terribly big, it does support threads though. NYU made a free Ada compiler in the 90s, it's part of gcc now. Ada's problem wasn't only compilers, it was the culture. Hackers hate COBOL, it's still routinely used to cutdown a language ("Java is the new COBOL") yet very few have ever used it but it has that rap. Ada is a DoD specified language that was designed with real software engineering problems and science in mind, it has a bad rap because of that. It's a different world now, the tooling alone changes the equation (at the time both Ada and pascal were seen as too verbose, begin and end were a lot more letters than braces, now our editors do that stuff for us..) being a DoD specified cousin of pascal is what hurt Ada, then there was the compiler selection... It always seems like Ada is ready to be attractive, there is a community around rust and go though.
