Tommy Caldwell recreated the dyno on the Dawn Wall with plastic holds. Alex Honnold didn't practice the boulder problem on Freerider on the ground to my knowledge, he set it at a gym later for fun though.

Are the plastic holds themselves an example of the technology we're thinking about here?

The gym is, itself, a technology that has pushed the envelope on climbing. When I was learning in the 90s there was no gym where I was and if I wanted to practice I had to climb buildings. It's much easier now to find good places to work out climbing technique without traveling to the cliff.
