word processors are themselves obsolete in a world where the result isn't printed.
I don't see that.
When contracting I am always being sent Word docs for this and that. There's rarely a need for anyone to print them; the value seems to be in the ability to control layout and highlighting, embed nicely formatted tables, and include images or diagrams, all as viewed on a computer.
Even if we assumed no one was ever going to print these documents, only pass them around to a limited audience, what would be a better tool for the average person helping out on a project? If not Word then almost certainly something very much like it.
