My hypothesis is that we have a collective knowledge that we tend to forget and that the new generation often doesn't understand, or takes for granted, the foundations of the infrastructure we use and sometimes tries to apply concepts they've just learned without understanding the subtlety and complexity of the ecosystem as it exists. This tends to happen with younger people which is why I was asking the age of the OP.
You being the OP that you're referring to yourself in the third person? And you're trying to insinuate that I'm an idiot criticizing an expert? It'd be nice to say so instead of saying this so obliquely. I've insulted you. Sorry. I was and am arguing in good faith. Please show me the same courtesy.
It's great that you worked on all these assemblers, macro languages and operating systems but I stand by my point. There are many DSLs in and around "operating systems" that you've failed to identify.
Maybe the crux of disagreement is that you have in mind a particular type of DSL for a tranche of operating system engineering that you haven't properly articulated. Considering your oblique insult and response, I would guess this is the case.
