This is exactly what your grandparent (and parent to some extent) comments are arguing against.
There aren't 2 different kinds of research, kind A that is never gonna go anywhere and kind B that is visionary. The vast majority of the advancement of knowledge has been what academia has always valued: probably never gonna go anywhere, but might push the envelope by an inch or a millimeter. The whole reason you have to research a thing is you don't know whether it's gonna go anywhere.
Which isn't how we think in industry, not even in industry R&D. We have to know it'll probably to go somewhere, or at least have a small chance of going really far. That's the only way to get a profit in expectation.
But work that will probably go nowhere or even if it does go somewhere, won't get very far, like most of scientific progress? The point of systems like tenure is to foster that, since industry can't.
I don't think you understand the point being made about different kinds of research. You are correct, it is not "kind that will never go anywhere" and "kind that is visionary".
But I do think we can separate "kind that is incremental improvement on existing systems" and "kind that is visionary change of existing systems". This is particularly true in computer systems research. It's common to see a paper where people tweak a small part of an existing system; I consider that incremental research, and it is necessary. But the value of such incremental research is dependent on the assumptions made by the researchers. Often, those assumptions are informed by impressions of what is important to the wider field of computing, and the author is saying those impressions are often misguided.
