I think it's reasonable to question the supposed invincibility of this thing, so not sure why you have been downvoted. These planes generally rely on a cumbersome sea borne platform which is a pretty juicy target for a hypersonic missile, and advances in radar systems are challenging stealth. If this type of weapons system is made obsolete by advances in technology or strategy that's a lot of eggs in one basket. However I don't doubt DARPA etc are coming up with weird and wonderful new concepts also. But the ingenuity and motivation of the Russians, Chinese etc. should not be underestimated. In certain areas their capabilities are superior.
