I think it's a pretty giant hurdle, and I don't think it's a strictly generational thing. Having been on both sides of the computational/experimental divide, I still fundamentally can't trust a result that has no experimental validation. At some point, even if you believe the computation's result, it has to be proved out in the physical world to be useful.
