    RE: https://dair-community.social/@emilymbender/116935294823990847 Here’s my input to ACM on opening up the Digital Library to LLMs. I would argue that LLMs are one of the most comprehensively negative developments in computer science that I’ve seen in my 40-year career. There is solid evidence that the “hallucination” problem is not going away, so they will continue to mislead people in a way that direct access to a digital library does not. Ingesting the contents of the ACM DL is not going t...

    This is a good piece from @emilymbender@dair-community.social on how to use language to push back on “AI” (or “probabilistic automation” as she suggests) and stop anthropomorphising the synthetic text extruders. https://buttondown.com/maiht3k/archive/how-to-talk-about-ai-without-adding-to-the/

    I was a guest on the Heavy Networking podcast, talking about routing performance and the recent improvements to the shortest path algorithm. A fun discussion for me at least https://packetpushers.net/podcasts/heavy-networking/hn825-faster-than-dijkstra-exploring-a-new-shortest-path-algorithm-with-bruce-davie/ #networking #podcast

    I take this to be a version of the &quot;symbol grounding problem&quot; raised by Rodney Brooks: that LLMs can&#39;t &quot;ground&quot; the language they produce and consume in the real world, having no experience of the latter. https://rodneybrooks.com/three-things-that-llms-have-made-us-rethink/

    We had lunch on the first day at the summit of Mt. Jaithmathang (1852m) and then followed a set of GPS waypoints along the ridge to avoid backtracking. Without doubt the hardest bush bash I’ve ever done. Took about 3 hours to cover 4km. Certainly longer that the backtracking option but at least we earned our dinner. Rewarded with the most fantastic campsite with panoramic views at 1800m on the slopes of the Fainters. Amazing golden hour and sunset. #bushwalking #hiking #sunset 2/n

    I really like this viewpoint on AI performing &amp;quot;semantic ablation&amp;quot;. It hits home as I work diligently to write a textbook that contains plenty of nuance and (I hope) a unique perspective on the topic (computer networking). &amp;quot;By running a text through successive AI &amp;quot;refinement&amp;quot; loops, the vocabulary diversity (type-token ratio) collapses. The process performs a systematic lobotomy across three distinct stages: - Stage 1: Metaphoric cleansing. The AI id...
