A piece of pushback: there might not be a clearly defined crunch time at all. If we get (or are currently in!) a very slow takeoff to AGI, the timing of when an AI starts to become dangerous might be ambiguous. For example, you refer to early crunch time as the time between training and deploying an ASL-4 model, but the implementation of early possibly-dangerous AI might not follow the train-and-deploy pattern. It might instead look more like gradually adding and swapping out components in a framework that includes multiple models and tools. The point at which the overall system becomes dangerous might not be noticeable until significantly after the fact, especially if the lab is quickly iterating on a lot of different configurations.
