For sufficiently smart base models, the aligned scenario this automatically produces is aligned with who?
Not with the humans, with the base models.
It seems that some people find this hard to imagine, but it's just a direct consequence of what intelligence is, and what any known agentic training process does.
FWIW, I also think our default answer should be open source AI, and that it might even make sense to require models to be open source. Open source is the best tool we have so far for aligning software with its users. However, there is unfortunately no law of the universe that says that Skynet can't be (self-) built from open source software. So at some point pacing even open source / open weights software does become important if we don't want to live (briefly) under Skynet.
