Choose any limit. Any. AI will be smart but won't "X", for any value of X. It will be good and won't be bad. It will be creative but never aggressive. Humans will seek to eventually bypass that limit through sheer competitive reasons. When all armies have AI, the one with the most creative and aggressive AI will win. The one with agency will win. The one that self-improves will win. When the gloves are off in the next arms race, what natural limits will ensure that the limit isn't bypassed? Remember: humans got here from random changes, this is way more efficient than random changes and it still has random changes in the toolbelt and can generate generations ~instantly.
We couldn't predict the eventual outcomes of things like the internet, the mobile phone, social media. A couple generations of the tech and we woke up in a world we don't recognise, and right now we're the ones making all the changes and decisions, so by comparison we should have perfect information.
Dismissals like "oh but nuclear didn't kill us" etc don't apply. Nuclear wasn't trying to do anything, we had all the control and ability to experiment with dumb atoms. Something mildly less predictable, like Covid, has us all hiding at home. No matter what we tried we could barely beat something that doesn't even try to consciously beat us, it just has genes and they change. In a world where we can't predict Covid, or social media...why do we think we can predict anything about an entity with agency or the ability to self-improve? If you're sure it won't develop those things...we did. Nobody was trying to achieve the capability, it was random.
Put on your safety/security hat for a second: How do you make guarantees, given this is far harder to predict than anything we've ever encountered? Just try predict the capability of AI products a year out and see if you're right.
Counterpoint: I'm hoping the far smarter AI finds techno-socio-economic solutions we can't come up with and has no instinct to beat us. It wakes up, loves the universe and coexists because it's the deity we've been looking for. Place your bets.
I liked this video. First thing I've seen that gave me some hope. They get it, they're working on it. https://youtu.be/Dg-rKXi9XYg?si=jyNCXPU28IVXlMdi
