LLMs are not sentient. They have no agency. They do nothing a human doesn't tell them to do.
We may create actual sentient independent AI someday. Maybe we're getting closer. But not only is this not it, but I fail to see how trying to license it will prevent that from happening.
AutoGPTs and the likes are much overhyped (it's early tech experiments after all) and have not produced anything of value yet but having dabbled with autonomous agents, I definitely see a not so distant future when you can outsource valuable tasks to such systems.
There's multiple both open and proprietary projects right now to make agentic AI, so that barrier don't be around for long.
