1. What are we actually talking about, slowing development or slowing public release? I can't imagine the the US is keen to slow actual development when we have adversarial state-backed labs continuing development. Seems to me that this is a global pact or it's nothing. Stopping a single lab, even if it's the current leader, won't put the genie back in the bottle.
2. Unless they stop actual advancement, isn't the risk essentially identical? At this point, it's an arms race between the lab and its own model. I don't think it far fetched to think that it might successfully exfiltrate its weights, for example.
3. There are going to be factions who don't want to stop. Should we worry about them defecting to other labs or other countries?
