Time will tell. If the F35 gets the time is another argument all together.
I remember hearing the same sort of things when the F16 was introduced. My Dad had worked for General Dynamics, and had done some work on the F16 project. The F16 had an awful release with many crashes, and even pilot deaths. It was just to technologically advanced The program was using to many new and untried systems it was said. Every issue was reported in the news papers. Not to mention the cost over runs and production delays.
Now, I can't tell you that they were of the same magnitude or not, because I was just 12-13 y.o. when the F16 was introduced, but it does sound awful familiar.
Personally, I believe that even if the F-35 design turns out to be a good one, drones will eventually over shadow it, and it will be an inconsequential foot note in history.
