I generally agree with the article, however it reminds me of what my algorithmic competition mentor once said:

“So you know who java developer is? Someone who doesn’t know Java”.

While the emphasis was not on Java, but knowing a single language.

“If he could learn Java well he could very much learn C++”.

Again emphasise is not on C++ specifically, but any other language really.

Technology landscape changes, stack get more complex.

While we should not expect everyone to know everything all the time, we should expect most developers strive for fullstackness. A ideal perhaps never to be achieved .

If you know Java, you can learn C++ quickly.

But your knowledge of Java frameworks or Maven configuration will be quite useless for your new C++ project.
