I'm sorry this is just silly. You are saying no one should have opinions on policy except politicians? Politicians are experts on what policies are good?

I think they are more like people who are experts at getting elected and getting funded. For making actual policy, they usually just resort to listening to experts in the relevant field; economists, businessmen, and in this case robotics experts.

The robotics experts are telling them "hey this shit is getting really scary and could be stopped if you just stop funding it and discourage other countries from doing so." It is of course up to actual politicians to debate it and vote on it, but they are giving their relevant opinion.

Which isn't at all unprecedented, we do the same thing with countless other military technologies, like chemical weapons and nukes. Or even simple things like land mines and hollow point bullets. It's not like they are asking for totally new policies. They are more like, "hey this thing you are funding is really similar to these other things you have forbidden."

And nukes are banned btw. We don't make any more of them, we are trying to get rid of most of the ones we have made. We don't let other countries make them. We don't test them or let anyone else test them. And no one is allowed to actually use them.
