The original goal of the AI field was the construction of “thinking machines”, that is, computer systems with human-like general intelligence. For the last few decades, however, the majority of AI researchers have focused on what can be called “narrow AI” – systems with intelligence limited to specific, highly constrained tasks. In recent years more and more researchers have recognized the necessity – and feasibility – of returning to the original goals of the field. Increasingly, there is a call for confronting the more difficult issues of human-level intelligence, and more broadly “artificial general intelligence” (AGI).

"This left me wondering about two things, 1) what does knowledge really look like, 2) why are we always creating hierarchies in nature? The empirical evidence seems to defy us whenever we attempt that." 
It’s been a while since the last update, but be assured we’ve been very busy working away on the embodiment code and developing our virtual learning environment. With AGI-11 now in progress at the Googleplex, we’ve put together a few videos to give an outline of what we’re working on. There isn’t any overly advanced learning going on yet, but it gives you a feel for where the project is going.
First up is a video demonstrating a human controlled player navigating and interacting with the world. This world is built in Unity3D, so eventually we’ll be able to put this environment online, make it an iPad app, or whatever else, and let you guys interact and teach OpenCog directly.

Hackers are creating a way for citizens to build their own communication networks from the ground up, using computers, cellphones, and wireless routers. Such networks — called mobile ad hoc networks, or MANETs — would circumvent centralized communication hubs, enabling users to talk and share information in the face of a shutdown.

Large amounts of radioactive materials were released in the ocean offshore, but are staying contained, from the Fukushima Daiichi nuclear power plant accident in Japan. The word from the land is bad enough. As my colleague Hiroko Tabuchi reported on Saturday, Japanese officials have detected elevated radiation levels in rice near the crippled reactors. Worrying radiation levels had already been detected in beef, milk, spinach and tea leaves, leading to recalls and bans on shipments. Off the coast, the early results indicate that very large amounts of radioactive materials were released, and may still be leaking, and that rather than being spread through the whole ocean, currents are keeping a lot of the material concentrated. Most of that contamination came from attempts to cool the reactors and spent fuel pools, which flushed material from the plant into the ocean, and from direct leaks from the damaged facilities. Japanese government and utility industry scientists estimated this month that 3,500 terabecquerels of cesium 137 was released directly into the sea from March 11, the date of the earthquake and tsunami, to late May. Another 10,000 terabecquerels of cesium 137 made it into the ocean after escaping from the plant as steam. Chernobyl-induced radiation in the Black Sea peaked in 1986 at about 1,000 becquerels per cubic meter, he said in an interview at his office in Woods Hole, Mass. By contrast, the radiation level off the coast near the Fukushima Daiichi plant peaked at more than 100,000 becquerels per cubic meter in early April. While Mr. Buesseler declined to provide details of the findings before analysis is complete and published, he said the broad results were sobering. “When we saw the numbers — hundreds of millions of becquerels — we knew this was the largest delivery of radiation into the ocean ever seen,’’ he said. ‘‘We still don’t know how much was released.’’ Mr. Buesseler took samples of about five gallons, filtered out the naturally occurring materials and the materials from nuclear weapon explosions, and measured what was left. The study also found that the highest cesium values were not necessarily from the samples collected closest to Fukushima, he said, because eddies in the ocean currents keep the material from being diluted in some spots farther offshore.

"However, I believe there is a lot to be learned from working with and extending the current codebase on single powerful machines, or small networks of distributed machines. I think we can potentially get all the key cognitive algorithms of OpenCog working together in this way, which is really the main problem in the way of achieving AGI (IMO).... Once this is done, we may or may not wish to re-code various portions (or the whole thing), for use on distributed or parallel processors or for other reasons based on what we've learned by that point... But for now, I really feel the current codebase is quite appropriate for getting to the point of demonstrated human-like cognition in various simple situations, via cognitive synergy between learning algorithms associated with different memory types..."
