Milo Minderbinder,
I totally agree that in a perfect world that lots of different technologies would be developed and tested. Unfortunately companies need to make a profit to keep shareholders happy and to not go bankrupt, so development when their are no sales won't be perceived as being acceptable. The governments of today can't afford to fund such projects either. A slight generalisation there as it does happen, but on a small scale. We also rarely see the type of persons who are generous enough to aid such developments through magnanimity these days.
The Jaguar FBW aircraft was called Active Control Technology (ACT). Registration was XX765.
