DARPA Putting Skynet on a Fast Track

Filed under: Uncategorized — rrtucci @ 8:35 pm

Imagined conversation:

General Pershing: To build a decent Skynet, we will need a fleet of unmanned submarines that can deliver unmanned aerial and naval drones to the doorstep of any country that disagrees with us. We’ll also need a network of laser-armed sky-level platforms (maybe satellites or balloons or towers) to shoot down enemy drones. Drones are cheap to build so we can expect our enemies to use them against us in the near future.

DARPA official: But general, what if the public objects strongly to this?

General Pershing: Psss. We’ll just make it a top secret project. That way nobody can criticize us, and journalists will have almost no information to report.

DARPA official: Right ho, general. Let’s pay University XXX and Company YYY 100 billion dollars to build one. Hydra sounds like a really cool name for it, don’t you think? But who is going to control this myriad of devices. Nuclear missiles too, right?

General Pershing: No problema! This will all be controlled effortlessly by our Skynet quantum computer AI, now being developed by University XXX and Company YYY

DARPA official: Hot dog, General!

DARPA’s ‘Hydra’ would be an undersea drone carrier,
by Devin Coldewey NBC News (July 23, 2013)


The “(Hydra) Proposer’s Day” event, at which further details will be announced and initial ideas heard ahead of a broader announcement, will be held at Johns Hopkins University on Aug. 5. Darpa will be accepting proposals on Aug. 5

Solicitation Number: DARPA-SN-13-42

Our INESCAPABLE??? Skynet Future

Filed under: Uncategorized — rrtucci @ 6:01 pm

Great American patriots like Bradley Manning and Edward Snowden taught us nothing.

From the prophetic 1984 film The Terminator

The Terminator: The Skynet Funding Bill is passed. The system goes on-line August 4th, 1997. Human decisions are removed from strategic defense. Skynet begins to learn at a geometric rate. It becomes self-aware at 2:14 a.m. Eastern time, August 29th. In a panic, they try to pull the plug.

Sarah Connor: Skynet fights back.

The Terminator: Yes. It launches its missiles against the targets in Russia.

John Connor: Why attack Russia? Aren’t they our friends now?

The Terminator: Because Skynet knows the Russian counter-attack will eliminate its enemies over here.

One of the following 2 captions will someday fit:Sarah C. Aaronson tries desperately to dismantle the MIT Skynet, a quantum computer AI built for DARPA by the MIT computer science department, under the leadership of her father, Scott Aaronson. Sarah C. Rose tries desperately to dismantle the Google Skynet, a quantum computer AI built for DARPA by Google-DWave, under the leadership of her father, Geordie Rose.

Jumping the Chaaaaasm

“Leaping the Chasm” (1886) by Ashley Bennett, son of photographer Henry Hamilton Bennett, jumping to “Stand Rock”. See http://www.wisconsinhistory.org

Right on the heels of having swum across the River Shannon, the Johnny English Olympian in me was looking for a physical feat to perform next, one that was equally challenging. As a child, I had been told of a strange natural formation in the Wisconsin backwoods, consisting of twin pillars of rock about 40 feet high, standing side by side, maybe 7 feet apart. There was no doubt that the chasm between the two pillars could be jumped. An early photograph from the 1880’s, long before Photoshop, of a Victorian man captured forever in mid flight between the two pillars proved that the jump was possible (assuming that he reached the other side safely). In my deranged mind, I began to identify the twin pillars with CAUSALITY and CORRELATION and the wonderfully agile Victorian man jumping the chasm with Judea Pearl. And then it hit me. For my next feat, I would attempt to jump between those two pillars in a new way. 

In the Victorian era, Judea Pearl had accomplished his jump wearing classical shoes (classical Bayesian networks). Wonderful shoes to be sure, but in the modern era, classical shoes would not do. The Victorians mastered steam, thermodynamics, classical physics. But their era had been followed by 100 years and thousands of glorious, successful corroborations of quantum mechanics which had established beyond a shadow of a doubt that Nature is not classical dammit, it’s quantum. I would have to use modern, quantum shoes (quantum Bayesian nets) for my jump. If the jump could be accomplished with classical shoes, there was no doubt in my mind that it could also be accomplished with quantum shoes, and how much more wonderfully entangled that would be.

Check out my new paper in my continuing saga to jump across the chasm of causality and correlation using quantum Bayesian nets for shoes. 

An Information Theoretic Measure of Judea Pearl’s Identifiability and Causal Influence, (54 pages), by Robert R. Tucci (http://arxiv.org/abs/1307.5837)

This is my second paper on the subject of Judea Pearl do-calculus. So far, in both papers I have only used classical shoes. I’m warming up with classical shoes, laying down the foundation for my quantum jump. I think I will try a quantum jump on my next paper.

As a famous 1989 Spike Lee, Michael Jordan commercial explains, if I manage to reach the other side without plummeting to my death, you’ll know for sure that “it’s gotta be the (quantum Bayesian network) shoes”.

One Hundred Piranhas Unleashed on Academia

Filed under: Uncategorized — rrtucci @ 7:19 am

A single piranha might give you a nasty bite, but it won’t kill you (their mouth is no larger than a quarter)… A school of 100 piranhas, on the other hand, might eat you up in a few minutes (if James Bond movies are to be believed).

Check out this amazing news item:

D-Wave Systems achieves 100 patent milestone


…D-Wave Systems Inc., has achieved an important milestone having been granted its 100th patent by the United States Patent and Trademark Office recently.

D-Wave Systems’ patent portfolio was also rated #4 in the Computer Systems category by IEEE Spectrum this past December, just behind computing giants IBM, HP and Fujitsu.

Methinks that in the future, these 100 piranhas are likely to cause legal confrontations between D-Wave and some academic institutions, many of which hate D-Wave.

Academics are always belittling or ignoring other people’s patents (even though they and universities often patent their own ideas). They are even more likely than usual to belittle and ignore the patents of a company that they a priori have a low regard for, D-wave.

D-wave is likely to use its patent portfolio as leverage to get more government funding, especially from defense and spy agencies like ARO and IARPA. The academics won’t be too happy about that because they feel they are entitled to that money.

I think 100 patents for adiabatic quantum computing is a huge overkill, really mind boggling. However, I can understand D-wave’s urge to protect itself. The QC academic community has very low moral standards; cheating, lying and playing the system are common practices in those circles, and those who don’t cheat and lie often turn a blind eye to it or even defend those who do. So I can understand why D-wave might be paranoid.

Interesting facts about piranhas:

Piranhas are also called caribes, after the Caribe indians. The Caribe indians were a tribe of warriors that practiced cannibalism. They came originally from Venezuela and its nearby island, Aruba. However, they were skillful canoeists that ranged widely throughout the islands of the Caribbean sea (which is obviously named after them), where they raided and munched on other indian tribes.

Piranhas are commonly eaten by humans throughout the Amazon basin. However, fishermen beware: If an individual piranha is caught on a hook or line, it may be attacked by others from its school before you pull it out. It is not rare to find a piraña with one eye missing due to a previous encounter with other pirañas of its fish school (fish school bullies).

Whither to Simulate or Compile

Filed under: Uncategorized — rrtucci @ 4:49 pm

I’m currently trying to finish a paper on Judea Pearl do-calculus. It’s 99% finished, but the last 1% keeps eluding me.

Recently, I’ve been reminded of the issue of whither to use the word “compile” or “simulate” in quantum computing. So let me rerun a post which I wrote 4 years ago about the matter. (I’ve changed it a little bit, improved it I hope, for this occasion).

I, Grammaticus, speak about simulation
