I'm not trying to be argumentative, I'm just trying to clarify my perspective, which I think the author shares with me and I feel is not being understood. We know what has worked in the past. To me the author is saying functional programming with language features helpful for parallel programming is a better path to take. If I say I believe electric cars are better suited for the future and you say millions of internal combustion cars exist and work just fine, you haven't told me anything I don't already know or addressed features of electric cars that you feel make me wrong. That a large electric car infrastructure doesn't exist yet also doesn't disprove anything. The internal combustion engine is going away and so is C++. That's my opinion.
