Yes, I agree. I think you misunderstood me though. I wasn't saying refrigerators aren't an attack vector. I was using them as a comparison to make the point that a policy of blocking internet access is far less effective on an autonomous robot with vision and hearing (since it can easily communicate in other ways) than for a refrigerator (where the policy actually has a good chance of disabling the attack).

You need something more than just disabling internet access if you don't want robots sourced from military rivals to remain a strong risk.
