Situational awareness or situation awareness, often abbreviated as SA is the understanding of an environment, its elements, and how it changes with respect to time or other factors. It is also defined as the perception of the elements in the environment considering time and space, the understanding of their meaning, and the prediction of their status in the near future.[1] It is also defined as adaptive, externally-directed consciousness focused on acquiring knowledge about a dynamic task environment and directed action within that environment.[2] Situation awareness is recognized as a critical foundation for successful decision making in many situations, including the ones which involve the protection of human life and property, such as law enforcement, aviation, air traffic control, ship navigation,[3] health care,[4] emergency response, military command and control operations, transmission system operators, self defense,[5] and offshore oil and nuclear power plant management.[6] Inadequate situation awareness has been identified as one of the primary causal factors in accidents attributed to human error. https://en.wikipedia.org/wiki/Situation_awareness (more)

We predict that the impact of superhuman AI (ASI) over the next decade will be enormous, exceeding that of the Industrial Revolution. We wrote a scenario that represents our best guess about what that might look like.1 It’s informed by trend extrapolations, wargames, expert feedback, experience at OpenAI, and previous forecasting successes. by Daniel Kokotajlo, Scott Alexander, Thomas Larsen, Eli Lifland, Romeo Dean. https://ai-2027.com/ Published Apr'2025.

Intergalactic Computer Network or Galactic Network[1] (IGCN) was a computer networking concept similar to today's Internet. J.C.R. Licklider, the first director of the Information Processing Techniques Office (IPTO) at The Pentagon's ARPA, used the term in the early 1960s to refer to a networking system he "imagined as an electronic commons open to all, 'the main and essential medium of informational interaction for governments, institutions, corporations, and individuals.'"[2][3] An office memorandum he sent to his colleagues in 1963 was addressed to "Members and Affiliates of the Intergalactic Computer Network".[4] As head of IPTO from 1962 to 1964, "Licklider initiated three of the most important developments in information technology: the creation of computer science departments at several major universities, time-sharing, and networking."[3] By the late 1960s, his promotion of the concept had inspired a primitive version of his vision called ARPANET. ARPANET expanded into a network of networks in the 1970s that became the Internet.[2]* https://en.wikipedia.org/wiki/Intergalactic_Computer_Network (more)

The OpenAI report is very straight man, corporate, checking boxes, some good prosaic stuff in the action plan but distinct lack of new details or deep reflection. They understand they have a problem, but they think the problem is mostly prosaic. It’s not. (more)
