To add a few more exotic cases that affect things. Keep in mind that by default new languages fail. To succeed, many things have to all go right at once, and this implies that therefore there is not one single element that, if gotten right, means the language will therefore be successful (it's rather the opposite: If even one of the key factors is wrong, it'll probably fail). * It's just a guesstimate, but one of those factors that caused java to be successful but-for (as in, if it hadn't had this, it wouldn't have been a success): It copies C style religiously anywhere it could get away with it. This caused some damage to the language that it has fixed in the past decade (such as the style and behaviour of `switch` being so bizarre - but it religiously follows exactly how it works in C!) * Some languages end up failing partly due to community outlook. Scala is somewhat well known for having a core community that is highly aggressive and elitist, or to be a bit milder, to be 'less accepting of newbies with a limited understanding of programming concepts' than is optimal'. And in addition to that, they are in contrast to the java ecosystem ready to drop support for stuff quickly, meaning: Real life actual use of scala as a basis means you're either working with a hopelessly obsolete codebase or you're spending time refactoring it every other month pretty much. Scala's adoption is fading and never got anywhere near its hyped future. * If a language is 'native to a platform' which I define as: "If the shepherds/owners of that platform were to write a basic app for their own platform, what language would they write it in? That's the 'native to that platform' language", then it tends to succeed even if it is not fun and not very well designed and even if transpilers exist. This is sufficient explanation for me for the success of javascript: It is the native-to-the-platform language if the biggest platform around. These all fit within the thesis. They're all (last one is debatable) very human factors.

On scala, I think there were several factors that led to it stalling out in the mid to late aughts. I am not convinced the community was the root cause. I think more significant was the scala 3 transition. When they were still near the peak of the hype cycle, the core team decided to spend more than five years rewriting the compiler. In my opinion, while there were good reasons to do a rewrite, they focused on the wrong things if widespread adoption was the goal. The biggest problems with scala were compiler and sbt performance, as well as related dev tooling. The new scala 3 compiler had to first approximation equivalent performance to scala 2 and they did nothing to improve the build system. In the meantime, other languages that overlapped with scala in various ways rose up: kotlin, typescript and rust come to mind. The unique value proposition was diluted, and the poor tooling experience persisted. Now, that's not to say that the community was not also a factor in scala losing momentum. I agree with your take. At the same time, that elitist community was also building cool and useful stuff that significantly improved upon what was available in other ecosystems so I think it was a double edged sword. Even today, there are things that are easily done in scala that are useful, elegant and impossible to do directly in most of its peer languages. It may never have reached truly mainstream ubiquity but I think with better technical decision making, the language could have remained very strong its niche.
