My understanding is that the Osprey's early issues were mechanical and training issues and not issues with the concept (propshaft issues, pilots not trained properly, poorly engineering wiring harnesses, etc) . Those things were fixed and now the Osprey is used quite a bit. I even saw one fly over my home the last time Obama visited. Most of the current and next gen fighters have some level of V/STOL built-in as well. I think we're pretty far from what you're describing, which was maybe 15-20 years ago. Lets remember that the design team for the Osprey started in the early 80s and the original prototypes are from the 70s. The Bell XV-15 prototype first flew in '77 and then the larger version as part of this proposal flew in '83. Aircraft engineer has gone a long way since. We're able to do much more today.
