Narrow-AI driverless cars will probably not decide that they need to take over the world in order to get to their destination in the most efficient way. Even if it would be better, I would be very surprised if they decided to model the world that generally for the purposes of driving.
There's only so much modeling of the world/general capability you need in order to solve very domain-specific problems.
The reason for expanding a narrow AI is the same for a tool agent not staying restricted; the narrow domain they are designed to function in is embedded in the complexity of the real world. Eventually someone is going to realize that the agent/AI can provide better service if they understand more about how their jobs fit into the broader concerns of their passengers/users/customers and decide to do something about it.
I know people have talked about this in the past, but now seems like an important time for some practical brainstorming here. Hypothetical: the recent $15mm Series A funding of Vicarious by Good Ventures and Founders Fund sets off a wave of $450mm in funded AGI projects of approximately the same scope, over the next ten years. Let's estimate a third of that goes to paying for man-years of actual, low-level, basic AGI capabilities research. That's about 1500 man-years. Anything which can show something resembling progress can easily secure another few hundred man-years to continue making progress.
Now, if this scenario comes to pass, it seems like one of the worst-case scenarios -- if AGI is possible today, that's a lot of highly incentivized, funded research to make it happen, without strong safety incentives. It seems to depend on VCs realizing the high potential impact of an AGI project, and of the companies having access to good researchers.
The Hacker News thread suggests that some people (VCs included) probably already realize the high potential impact, without much consideration for safety:
Is there any way to reverse this trend in public perception? Is there any way to reduce the number of capable researchers? Are there any other angles of attack for this problem?
I'll admit to being very scared.
