A lot of people have a lot of concerns with AI, its capabilities and with how it is used now and what it will lead to in the future. For good reason. But the question is, do we have a strategy that is actually useful? If so, what is it? I think nature shows us some answers in ecosystems.
Diverse ecosystems can absorb shocks. Diverse ecosystems are a sign of health of that ecosystem. When an invasive species comes into a healthy, diverse, ecosystem it doesn't mean that it isn't disrupted, but it does mean that it is far more likely to emerge with a lot of its diversity intact. In fact, it is likely to emerge even stronger because it can absorb that new shock and incorporate it, adding to its diversity. The balance may be changed, but the ecosystem survives or even thrives.
Nature also likes to show us that artificial barriers rarely last. You want to control a river? Good luck. It take constant maintenance to hold that flow in place and even then you are likely to get extremes that are made worse by your efforts because, eventually, somewhere in the system fails in a way you didn't anticipate. Then the water comes rushing in. Artificial barriers often have a way of building up tension over time, not reducing it, so that when a failure eventually happens it can be catastrophic. In other words, you had better really understand the system you are trying to control or else you can make things actively worse.
Relating this to the world now means, I think, that our best chance to minimize long term shock and maximize the chance that the diversity we have around us survives is to try to grow as healthy of an ecosystem as we can as quickly as possible. Lots of models large and small in lots of different hands is, I think, a better solution than artificial barriers restricting the variety and diversity of models and users. I think this is closer to an ecosystem solution and has a shot at working. Basically, I highly doubt we understand this situation enough to do a good job of controlling it with artificial barriers. Instead I think we are more likely to build catastrophic imbalances than we are to create the healthy ecosystem we really need.
