Can you imagine the sheer horror of being stuck in your body and unable to communicate? Being literally incapable of telling someone that you're in pain or where it hurts, for every waking second? Or, knowing that the end is near, not being able to tell your children that you love them? Or that you're sorry for not being a better parent?
May none of us ever need such technology.
We can all see how it can be used for good but we should never blind ourselves to the reality that it will also be used for evil without firm guardrails and tight controls.
It's probably best in the current environment if you refrain from making any more of the "think of the children" type of arguments. We all understand where that leads.
Alas, propaganda playbooks don't update that often.
