I wonder also if that possibility of unsafety just doesn't matter much to a lot of people. After all, lisps have been around forever and even today JS and Clojure are popular when the possibility of doing unsafe things is extremely easy in a language where there are no type checks. So perhaps many developers just don't worry so much about compiler checks and instead enjoy the flexibility of "weak" or "no" typing, at the possible expense of safety. And maybe all of that is gradually changing. I really really love Clojure, but find static typing very useful; but also, it's great to throw it away when you feel confident enough to do so, and perhaps a lot of developers just like this, shall I call it "cowboy", style?
