So, you're talking about idealistic pie in the sky theoretical convergence, and I'm talking about here-and-now practical convergence. (which isn't actually a criticism on my part, I often talk about that kind of "theoretical/idealistic/as-it-should-be" type of technology as well, but as Mahan pointed out wrt naval warfare, if you don't keep yourself fully immersed in both the theoretical and the practical, you're going to have problems .... practical beats theoretical, but the balance beats the pants off of both of them)
