I wish it were so simple, yet I think the rapid advances in the last 10 years or so in Java, C++, and JavaScript, which developers have been expected to learn and keep up with, are sufficient to more than cast doubt on that. The changes on whole are nearly broad enough to count as new languages. If that's not enough, then there's the mobile development side of things, which have seen actual language shifts in Objective C to Swift and Old Java to Kotlin.
