Boxing is a human pitting their wits against a potentially hostile transhuman over a text channel and it is stupid.

That was how you did your boxing experiments, but I've never taken it to be so arbitrarily limited in goals, capacities, or strategies on either end. There is no reason you cannot put the AI in a box with some triggers for it venturing into dangerous territory, and this would be merely sane for anyone doing such a thing.

That is how they build prisons. It is also how they construct test harnesses. It seems as though using machines to help with security is both obvious and prudent.
