"Ideas that diverged too much from the existing successful tech had a huge obstacle in their way: they had to recreate all of the existing solutions in their new model.” You’re so right! There are great examples of companies that preserved the existing ecosystem of solutions (Facebook with PHP, Microsoft with C++, Google with Java and C++, maybe also Amazon with Perl 5 and C++). There are also great examples of successful companies that in a certain sense did or had to do things in an entirely new model (WhatsApp with the Open Telecom Platform, F5 Networks with their data center FPGA-powered hardware load balancers, Tesla and SpaceX, and so on). There are also great examples of companies that did both, where they preserved an existing ecosystem but also added another ecosystem on top to fix flaws (NeXT Computer with Smalltalk and C, Stripe with the modern version of that as Ruby and Go, Twitter with Ruby and Java, so on). Microsoft is the best example of a company that can succeed even with what seems like a crazy choice. Almost everything being written in C++ sounds insane to the point of being business suicidal, but they worked hard enough to make it work. If Microsoft can succeed in the ways that they have with C++, and if Facebook could succeed for as long as they did with PHP, and Instagram can allegedly succeed with Django[1], then anyone can succeed with anything as long as you can endure the stress that a seemingly peculiar decision might cause you. And those standard ecosystems that they chose all had immense benefits, they just also had some pretty immense weaknesses as well (Powering 500 million daily users primarily with Python scripts?? That just seems pretty crazy to me, if it’s true). [1]Still very unclear about how much Python actually powers the web services behind Instagram. <https://instagram-engineering.com/tagged/python> https://instagram-engineering.com/tagged/python>.

I don't see why writing an operating system and surounding tools in C++ is a crazy decision (I'm assuming you meant windows & desktop apps by saying microsoft). Certainly not in the early 90's, but if you have a big codebase of that already, sticking with it doesn't seem crazy to me. People make too much of a fuss over the differences between programming language. There are some important differences (whether or not memory safe is a big one, but it is hardly critical to a succful bussiness) but by and large the difference between using say php, python, etc for your program is superficial in the extreme.

The fact that many large and lucrative code bases are written in c++ should disabuse you of the idea that c++ is suicidal.

  “Many” is almost underselling it. It’s literally EVERY web browser that anyone uses. I don’t know where people get these ideas. OP has a shallow understanding of programming languages, software development, and their history.

    > It’s literally EVERY web browser that anyone uses. And is a fine example of path dependence. No one can write a browser in any other language not because C++ is necessarily better but because the activation energy to bootstrap to a useful browser is so large (for example, one must provide a smoking fast Javascript engine before one even considers the web page rendering pipeline). It will be interesting to see how much of the Firefox codebase gets taken over by Rust as time passes.

      Basically, C++ developers (like me) are stupid. We're like primitive species, stuck with C++ because we can't understand superior languages. The Lisp developers tried to bring us the light, but we chased them away by throwing rocks at them. Now the Rust evangelists are doing the same thing, but I'm afraid we might take a break from writing video games, stock exchange software, safety-critical software, CAD packages, web browsers, video codecs and the like, to throw rocks at them. My point is: maybe C++ actually _is_ the superior language. It can't be a coincidence that all the best software projects tend to be written in C++, and not in Haskell or whatever.

        Dunno. As a mainly C++ developer I think Rust is a real alternative because it tries to solve the same problems better. Lisp and Haskell do not solve the same problems. Huge Lisp codebases probably become hard to understand quickly, and both Lisp and Haskell don't produce very efficient code (or make it hard to produce efficient code).

It's almost like language choice doesn't matter at all...

  Language choice is an implementation detail. As long as the language isn't technically unable to do the job (ie you can't write a device driver in Python), it doesn't matter much. It may be intensely interesting to practitioners, but it's not a make or break decision. Use what makes the team comfortable.
