It naturally contains some of the buzzwords of the time, such as fourth-generation programming language (4GL). If you’re not familiar with that term, suffice it to say that the Wikipedia page lists several examples, and Cobol has outlasted most of them.
Lots of 3GL outlived most 4GL languages, C, C++, C# Java, Ruby, Python, and even newer languages like Rust and Go are 3GL. In fact so did plenty of 2GL (assembly languages).
Programming language generations are about usage and level of abstraction not about being obsolete.
