frog,
It isn't blue sky, that's your problem, you ascribe value to only what's made available....stopped at the fogbank which conceals the real value.
One day soon, DNAP will burst out of the fogbank, towing more than the eye can take in with a glance, or the glimpse sideways you're used to taking.
It will run over you and the other doubters who insist that the world consists of only what one can see.
You tout yourself to be a scientist, having faith only in what your senses feed back to your brain.
Yet, you resist peering into the microscope of behind the scenes development, to your financial peril.
Most scientists peer there knowing they will see something, you peer not, knowing there is nothing to see. Alas!!
