I don't think there's many technologies that are 30 years old that are still relevant today. Most programming languages themselves are younger than that: Python 1991, Java 1996, C# 2002, go 2012. C++ and COBOL are ancient enough but niche. If we look at tools/frameworks, the story is even worse because they were obviously created later (plus some time to gain traction). I think the industry will slow down and stabilize over the next 20 years. It will be fragmented in different area of expertise, but there won't be another 10 new languages or another internet revolution.
