I'd say we are already there but the pretty pictures are still very alluring. One example: Consciousness appears to be within grasp with the massive datasets already collected. The problem comes down to explaining, or reducing, consciousness in terms of that data. We might be able to show you what happens in the brain when you see beauty or feel pain, but that explains the experience of neither. The questions remain even as the science is the best it's ever been. I think this reality is much more glaring in modern physics.
