The pendulum is now swinging back to types. Because it's a pendulum, in 5-10 years the next hot productivity thing is going to be dynamic, type-free languages. I still remember when people were excited by the productivity gains from Ruby. "No time wasted wrestling with casts and typing".
Rather than a pendulum, I think the reality is that typed languages are now going through a significant period of evolution, especially with the advent of _gradual_ typing. TypeScript, for example, is just a superset of JavaScript, but with a compiler that's smart enough to infer many of the underlying types from context. The notion of rigorous, strong typing has always been marred by the concept of casting, but this…
