causal claim

A slow experiment-and-update workflow is infeasible because there are too few agents to reduce variance sufficiently, instrument transitions create waiting time, and synthesis or furnace time has physical limits.

In their words

The transcript segments this claim was taken from

“completely infeasible because you don't have enough agents to reduce the variance sufficiently. The rollout time is going between the different instruments you're waiting. There's just”
“There's just some physics limits of the experiments for the actual synthesis or furnace time.”
