I’m not willing to go to bat for Oberon, but large swaths of software engineering are done with no tradeoff analysis of different technologies at all. Most engineers know one imperative programming language and maybe some SQL. If you ask them what to use, they will simply wax poetic about how the one language they know is the perfect fit for the use-case.

Even for teams further toward the right of the bell curve, historical contingencies have a greater impact than they do in more grounded engineering fields. There are specialties of course, but nobody worries that when they hire a mechanical engineer someone needs to make sure the engineer can make designs with a particular brand of hex bolt because the last 5 years of the company’s designs all use that brand.

If a language offered a significant competitive advantage, such an analysis wouldn't be necessary. Someone would capitalise on it, and others would follow. There are selective pressures in software. Contingencies play an outsized role only when the intrinsics don't.

My point is that for most of the software world, selective pressures are much weaker than things like switching costs and ecosystem effects. The activation energy for a new tech stack is massive - so it's very easy to get stuck in local maxima for a long time.

		You call it weak selective pressures, but another way of saying it is low fitness advantage. And we can see that because the programming language landscape is far from static, and newcomers do gain adoption very quickly every now and then. In fact, when we look at the long list of languages that have become super-popular and even moderately popular - including languages that have grown only to later shrink rather quickly - say Fortran, COBOL, C, C++, JavaScript, Java, PHP, Python, Ruby, C#, Kotlin, Go, TypeScript, we see languages that are either more specific to some domains or more general, some reducing switching costs (TS, Kotlin) some not, but we do see that the adoption rate is proportional to the language's peak market share, and once the appropriate niche is there (think of a possibly new/changed environment in biological evolution) we see very fast adoption, as we'd expect to see from a significant fitness increase. So given that many languages displace incumbents or find their own niches, and that the successful ones do it quickly, I think that the most reasonable assumption to start with when a language isn't displaying that is that its benefits just aren't large enough in the current environment(s). If the pace of your language's adoption is slow, then: 1. the first culprit to look for is the product-market fit of the language, and 2. it's a bad sign for the language's future prospects. I guess it's possible for something with a real but low advantage to spread slowly and reach a large market share eventually, but I don't think it's ever happened in programming languages, and there's the obvious risk of something else with a bigger advantage getting your market in the meantime.
