Seem to me that Python has won. What I mean by that is that it is used almost everywhere and there is almost no compelling reason to use anything else. You want web? Django, plus a million other frameworks, all well tested and documented. Machine learning? Tensorflow, Keras or PyTorch. Scientific computing? Numpy.

For the last two decades people have complained about (C)Python not being multi-threaded, not jitted, not having tco, being to simplistic and so on. In practice it seem to have mattered very little. For the applications where it do matter, like if you are writing your own language vm, compiler (but see PyPy) or garbage collector, you have to ask "Yes, ok, but how often do you do that?"
