One difference is hardware overhang. When new AI technologies are created, many times the amount of hardware they need is available to run them.

However, if an international agreement was reached in advance, and some of the AGI sandbox problems were solved, we might be able to restrict AGI technology to a bounded amount of hardware for a time-if theoretical results which we do not have yet showed that was the appropriate course of action.

We have all kinds of work to do.
