Apple and google have both launched full blown general purpose programming languages, enough of them that I can't speak broadly about them all but they all have some degree of following and support outside those orgs.
So has MS for that matter. I don't see why supporting the compiler of a relatively niche language counts as funding and research but those things don't.
I don't think your argument holds: if universities were to stop producing research and instead started producing code, that would raise a lot of eyebrows.
MS has produced a lot of pure research. Google and Apple produce mostly code.
I guess it depends on like "what is the output of research?" which I admit is probably hard to define and definitely not clear to me.
But your comment seemed to assume "compilers are the output of research" so I went with that.
I don't know anything about microsoft's research or apple's or google's either. But again I just don't understand the distinction between "research" and "code" that's being made here. There might be a useful distinction there but you're not making it.
What other companies have the equivalent of Microsoft Research in terms of funding and in terms of research output?
Does Google come even close? And where is Apple on the list?
