I'm interested.
Why exactly does it upset you?
Lets say you are correct, and that it will all come to nothing.
So what?
Some people have invested a relatively tiny amount of cash that doesn't affect you personally and will at the very least advance some research in new technologies.
What's the big deal?
Compared to money that goes into normal military or aviation advances it is a tiny drop in the ocean, and it just might work which will be great.
Saying "it won't work, look at the historical precedent" misses the fact that all new technologies have some false starts. You cannot ever say that something will never work because it never has.
Being a Luddite is obtuse, but at least the original luddites had the excuse that the new tech was interfering with their jobs.
What is you guys excuse?
