Is it an existential threat As AI is being subtly melded into our daily lives by the Google , Apple , and Microsoft clouds there is continuing debate over whether it is or Isn’t an existential threat . This debate has been brought to a head by the sudden and unexpected firing of Open AI’s chief executive Sam Altman and has starkly exposed the philosophical rift in the AI community between those who are more or less concerned about the potential risks of its untrammeled development . How many , if any , guardrails should be in place I have

I want to point to an open source "Core Concepts" article in PNAS by David Adam that presents "the views of some psychiatrists who argue that the same bit of biology—genetics gone awry or some misplaced brain circuitry—could underlie the vast majority of humanity’s mental health problems. Studies have shown, for example, that many of the same genes seem to drive increased risk for autism, attention-deficit hyperactivity disorder (ADHD), bipolar disorder, major depression, and schizophrenia. They call this as-yet-unidentified common cause the “psychopathology factor,” or “p-factor” for short."

Monday , September 25, 2023 Emergent analogical reasoning in large language models Things are moving very fast in AI development . From Webb et al The recent advent of large language models has reinvigorated debate over whether human cognitive capacities might emerge in such generic models given sufficient training data . Of particular interest is the ability of these models to reason about novel problems zero-shot , without any direct training . In human cognition , this capacity is closely tied to an ability to reason by analogy . Here we performed a direct comparison between human reasoners and a
