You can't actually stop AI development. It's a part of arms race now. If the USA listen to Musk, Russia and China will win.

So AI will become smarter and smarter. The only chance for us to survive is upgrading (especially neural prostheses). It may buy us some more time.

And then we will be gone. Hope nonbiological inhabitants of the Earth will be happier and more peaceful than the 'wise' animals (sapiens).
