I agree on your comment about "most efficient language". And I agree that the business-interest is micro-focused on monthly-cost versus yearly- or even multi-yearly-cost. I think those two things are at odds with each other. I think a lot of technical decisions are being made on a short-sighted business level. And I think a lot of people on the technology side have inculcated too much of the business message. I'm not arguing against ever using languages like Python or Ruby or PHP or whatever. But I think a lot of people make assumptions that their language choice doesn't matter. In a lot of the same ways that building an entire economy on carbon fuels was "easy", it only worked because of externalities. As a profession, we need to be taking a longer view of our craft. I don't think that it is true that it's impossible to make C++ secure. I don't think that it's true that--say--Java and C# are less productive than--say--Python or Ruby. On a surface level, certain things are easier, but once you start digging into real problems, there isn't much difference. And experienced developers in any language will be far beyond that surface syntax. I just think that, as a profession, we have our priorities way out of whack.
