The hypothesis I've had in my head since OpenClaw has been the following and I haven't seen contradictory evidence yet. Agents have a fundamental unresolvable tension between usefulness, safety, alignment, and accuracy. You have to restrict access to ensure an agent acts safely because alignment and accuracy cannot be perfect. But restricting access makes the agent less useful. You can play with the sliding scale and get more and more granular with access restrictions but at some point you need to draw some line. And then finally, even access restrictions cannot be made perfect, so improvements to model accuracy without corresponding improvements to alignment make detailed access controls less useful.

In other words, better models need blunter access controls which negates whatever improvement in utility they provide.
