Yes. Because if I'm having a bad day and I'm rude to the caller (not knowing it's a machine), I will feel guilt afterwards. The guilt will be unnecessary, because no human was offended. That may be a trivial case, but more generally our social contract is that we owe a duty of politeness and consideration to fellow humans. When you're interacting with another human, a big part of your brain is actively engaged in following social norms. By masquerading as human, machines co-opt this part of your brain and extract a duty that they don't deserve. I think every machine caller should be required to identify itself as such. Restaurants will still be happy to take reservations from them. If one calls me to sell me something, I can tell it where to go without any guilt.
