I believe Google has an AI ethics board due to MIRI/FHI/&c. influence. If you are correct about their long game, then MIRI&c almost certainly knows of it, and perhaps you could test out the hypothesis by looking for shadows in those organizations' strategy reports or something if you're truly interested. May or may not be a great idea to shout the results from the rooftops, however.
I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
