The last invention we will ever need

is a super smart robot that can invent stuff. This means it can invent an even smarter robot that can invent more stuff.

Althuogh sentient AI is possible (the human brain could be emulated perfectly by a computer since nuerons and synapses are well understood by science, its just a matter of putting them in the right place and finding 1,000,000,000 TB of RAM, and it would run slow as hell) as long as the AI outputs only allow it to print text to the screen, no matter how self-aware or intelligent it becomes it would only  be able to print text to the screen.  For it to launch missiles some idiot would have to reconfigure the outputs to give it access; it would never be able to do it on its own.
