I started using Python seriously only three years ago after 30 years of other languages and I didn't find it very simple. Maybe the core of the language is simple but the standard library and many other important modules can be very complicated. Among similar languages Ruby and JavaScript are far simpler.

JavaScript used to be simple... But Promises, closures, prototype chains, and npm/modules/minification/webpack has added a massive amount of complexity to being able to just read and understand a bit of code.

Javascript isn't simple any longer. And I'm not sure Ruby is that simple, not once you dig into the advanced features.
