If it really sucked then people wouldn't use it. It's very easy to spot a universally bad tool. There are these screwdrivers with an integrated lamp to check if a wire is live or not. Only incompetent electricians use single phase testers. Amateurs buy them because they don't want to spend $30+ on a real two phase tester and that's fine because they are going to use them 10 times in the first week and then never again.

The reality is that the difference between general purpose languages aren't that great. Even when highly conservative languages like Java adopt functional programming elements, they don't really add capabilities, they only change convenience. Lambdas are nicer than anonymous classes but they are still equivalent in functionality. The situations in which you absolutely need a purely OOP or FP focused language are pretty rare. People need a language that does a little bit of everything but doesn't go too deep into either end. The problem with feature rich languages is that they are ripe for abuse. When someone discovers a feature for the first time they are going to test it out. People produce a lot of crap in their learning phase that should be thrown out but it ends up in production code bases.
