Sometimes I find myself extremely impressed with an LLM output and then I hate myself a little bit

Interesting Sunday morning read: an external history of Cyc and some of the symbolic AI work done over the decades of its development.

Cyc – Yuxi on the Wired
Obituary for the greatest monument to logical AGI. After 40 years, 30 million rules, 200 million dollars, 2000 person-years, and many promises, Cyc has failed to reach intellectual maturity, and may n...

Was forwarded this article by a colleague today as a counter-example to the FUD around AI and jobs. I think I understand the argument here—that we will use AI for tasks that it is comparatively better at—but... 1/
Plentiful, high-paying jobs in the age of AI
Comparative advantage is very subtle, but incredibly powerful.

18F was doing exactly the type of work that DOGE claims to want – yet we were eliminated shortly after midnight. Read our letter to the American people:

The choice to define a "compose" operator and implement query plans using decorators is bizarre. Not quite syntactically correct in the middle either. Lines like "Table(selfother either entirely with the other table or only the left)" seem like some of the thoughts got left in the implementation 2/2

Playing with DeepSeek-R1-Distill-Llama-8B on my Macbook in between meetings today and got this interesting output for a Python pull-based relational algebra implementation. 1/2

6/8. In science, and in institutions of learning like colleges and universities, there is a shared understanding that edicts should not go unquestioned—that we all have a duty to systematically investigate the world around us and to interrogate claims about it. We do not simply obey.

Was talking with one of my students this morning about designing a new query abstraction for a new hybrid graph-timeseries database platform, but he hadn't tried to run his tasks on existing graph and timeseries databases first.

Abstractions are born from pain, not from inspiration!

I enjoyed watching @simonwillison.net's interview on the Around the Prompt podcast (simonwillison.net/2024/Dec/2/t...), especially his point about how vital knowledge of software engineering and programming is to be productive with LLMs. As good as these models can be (1/n)
