I don't think that this is right. A programming language is useful to programmers if it's oriented around the structure of the _problem_ and not just the structure of the _physical machine_. For some tasks these coincide (especially if you care about performance) but I frequently find myself in situations where functional code is simple and the machine is irrelevant.
