I am self employed, and invested the lump sum of 800€ (+ screen that I already head) for a reasonably beefy desktop machine. I'm not saying that 32G is the minimum required to run JetBrains IDEs well; I'm saying 8G is not enough and 32G is definitely enough to run it alongside a bunch of containers and other stuff.

I agree that JetBrains stuff is resource hungry (maybe excessively so); to me it is still worth using it for Java, C#, Python, iOS and Android. For C++ I prefer Qt Creator (though I must say that the idea of switching to CLion and having a consistent IDE experience across all platforms that I work on is tempting).
