No, not yet, but those are long tail efforts. The technologies are the short term yield.
I don't know why you were getting down voted for this. Discovery during technological development of scientific instrumentation is one of the greatest returns on investment of funding pure science research. And like your sibling comment says, the pure science helps direct applied science, eg cutting edge materials science. Long tail, if for no other reason, because its a whole other development process that happens after the pure science.
