Funny thing is I would be far less terrified of it than a human if it were holding a machine gun because its human-like movement is so incredibly slow I would feel like I actually had a chance (even if I didn't).
However, if they embedded the machine gun into the bot itself (which I think is far more likely) then you could have instant targeting which shifts the terrifying back to the bot. It would also not look like it even has a gun depending on how they incorporated it and it could fire in multiple directions at once.
Ah, the future of war. So efficient and terrifying.
Seems to have been changed to "Do the right thing" to some extent when they changed to Alphabet [1].
Interestingly enough, I think that restructure also helps obfuscate where Google products are used. It's unlikely that any military robots would be Google branded. Instead they would probably fall under a relatively obscure Alphabet company that the average person would never relate back to Google.

Actually, it was 'don't be evil'. They've emphasized the difference in the past; but in any case, Alphabet replaced it with "Do the Right Thing"[1].
But yeah; Alphabet is probably unlikely to want to be associated with the US military.
