Yes, that's a deep conflict in the tech world, even beyond this topic. For example, does a manager select PHP because PHP programmers are commodities? Some managers tell me that's how they select technologies: how commoditized its labor supply is. (They consciously accept the price of technological conservatism, to avoid real risks.) I personally think it's important to weigh the various risks. Keeping in mind there are "opportunity costs". So for example, if I were to choose something like Datomic, it's almost certainly because I predict much greater productivity than alternatives. There are risks to giving that up, which I must consider. And there are ways to mitigate some risk. Like simply asking what happens if they go out of business. Much like investigating potential failure modes.
