Who cares? The valet could do any number of other attacks, like stealing the car, sabotage, adding a tracker, whatever. Threat modeling is important, otherwise security can harm one's own goals. Sometimes you have to briefly trust another person. I'd rather have an open shell inside a locked room when the alternative is no access at all.

I think its going to be tough for society to reconcile with the fact that we are not so unique as we thought. Maybe it never will. Some animals are self-aware. Plants and fungus can communicate with each other via underground networks. Some of them move, react to stimuli, communicate with others in their species, and are able to differentiate between their offspring and other neighbors of the same species. Is it really any different to be a vegan or a carnivore?
