^ Indeed. If I invented a machine from scratch that I had reason to believe possessed true and testable intelligent self-awareness, I'd be very careful who I showed it to or told about it. The institutions most willing and able to make something like this happen have a lot of good reasons to be secretive about it. This is one of the main themes of the original novel Frankenstein.
It's not so tinfoil hat to suppose that something close to AI has already been invented, and only an inner circle of highly trusted US military elites, Sony executives, or rogue scientists in a compound in Siberia even have a clue it exists. It's the kind of invention that you wouldn't want the public to know all the details on until they'd already fully accepted many technological applications of it without realizing it. This is exactly how other controversial and existentially scary technologies have snuck in the back door to public acceptance, like nuclear weapons and genetically modified food.
