How long do you think it would take for the US government to build 100 million killer robots?
I don't believe that it ever will.
Technologies become less expensive over time, and as we progress, our wealth grows. If we don't have the money to produce it at the current cost, that doesn't mean they'll never be able to afford to do it.
If the US spends 6,000 USD in maintenance per robot, that would eat up the entire US military budget. 6,000$ is almost certainly a severe underestimate of the cost of operating them, by roughly 3 orders of magnitude
You didn't specify a time period - should I assume that's yearly? Also, do they have to pay $6,000 in maintenance costs while the units are in storage?
and anyways, that neglects a huge number of relevant factors: the cost of purchasing an MQ-1, amortized over a 30-year operating period, is roughly the same per year as the operating cost; money also needs to be spent doing R&D; non-robot fixed costs total at least 6% of the US military budget; much of US military spending is on things like carriers or aerial refueling or transports whose robot equivalents wouldn't be 'killer robots'; etc. (The military budget may go up over time, but the cost per plane has risen faster than the military budget since WWII, so if anything this also argues against large numbers of robots.)
Okay, so an MQ-1 is really, really expensive. Thank you.
An alternative date: I would expect the USAF to be majority unmanned by 2040 +- 5 years (50% bounds, most uncertainty above); this is roughly one lifecycle of planes forward from today. (Technically it's a fair bit less; but I'd expect development to speed up somewhat.) I would expect the US Army to deploy unmanned ground combat units in serious numbers by 2035 +- 5 years.
What is "serious numbers"?
I would expect the USAF to remove humans from the decision making loop on an individual plane's flights in 2045 +- 5 years; on a squadron, including maintenance, command, etc, 2065 +- 5 years; above that, never.
What do you mean by "above that, never"?
Sorry I didn't get to your other points today. I don't have enough time.
P.S. How did you get these estimates for when unmanned weapons will come out?
A new TED talk video just came out by Daniel Suarez, author of Daemon, explaining how autonomous combat drones with a capability called "lethal autonomy" pose a threat to democracy. Lethal autonomy is what it sounds like - the ability of a robot to kill a human without requiring a human to make the decision.
He explains that a human decision-maker is not a necessity for combat drones to function. This has potentially catastrophic consequences, as it would allow a small number of people to concentrate a very large amount of power, ruining the checks and balances of power between governments and their people and the checks and balances of power between different branches of government. According to Suarez, about 70 countries have begun developing remotely piloted drones (like predator drones), the precursor to killer robots with lethal autonomy.
Daniel Suarez: The kill decision shouldn't belong to a robot
One thing he didn't mention in this video is that there's a difference in obedience levels between human soldiers and combat drones. Drones are completely obedient but humans can throw a revolt. Because they can rebel, human soldiers provide some obstacles to limit the power that would-be tyrants could otherwise obtain. Drones won't provide this type of protection whatsoever. Obviously, relying on human decision making is not perfect. Someone like Hitler can manage to convince people to make poor ethical choices - but still, they need to be convinced, and that requirement may play a major role in protecting us. Consider this - it's unthinkable that today's American soldiers might suddenly decide this evening to follow a tyrannical leader whose goal is to have total power and murder all who oppose. It is not, however, unthinkable at all that the same tyrant, if empowered by an army of combat drones, could successfully launch such an attack without risking a mutiny. The amount and variety of power grabs a tyrant with a robot army of sufficient power can get away with is unlimited.
Something else he didn't mention is that because we can optimize technologies more easily than we can optimize humans, it may be possible to produce killer robots in less time than it takes to build armies of human soldiers and with less expense than training and paying those soldiers. Considering the salaries and benefits paid to soldiers and the 18 year wait time on human development, it is possible that an overwhelmingly large army of killer robots could be built more quickly than human armies and with fewer resources.
Suarez's solution is to push for legislation that makes producing robots with lethal autonomy illegal. There are, obviously, pros and cons to this method. Another method (explored in Daemon) is that if the people have 3-D printers, then the people may be able to produce comparable weapons which will then check and balance their government's power. This method has pros and cons as well. I came up with a third method which is here. I think it's better than the alternatives but I would like more feedback.
As far as I know, no organization, not even MIRI (I checked), is dedicated to preventing the potential political disasters caused by near-term tool AI (MIRI is interested in the existential risks posed by AGI). That means it's up to us - the people - to develop our understanding of this subject and spread the word to others. Of all the forums on the internet, LessWrong is one of the most knowledgeable when it comes to artificial intelligence, so it's a logical place to fire up a discussion on this. I searched LessWrong for terms like "checks and balances" and "Daemon" and I just don't see evidence that we've done a group discussion on this issue. I'm starting by proposing and exploring some possible solutions to this problem and some pros and cons of each.
To keep things organized, let's put each potential solution, pro and con into a separate comment.
