You are building scripts or expert systems, or applying a specific mathematical model or algorithm. Be specific about your tool or effort. Avoid calling it AI, and take this silly game away from those who would attempt to manipulate the course of progress by commandeering its labels. 3/4

You are training or inferencing, or using automated agents that build on these tools. You are using machine learning, or deep learning; you are using logic trees, hardcoded rules, lookup tables, key/value sorting with or without weights. 2/4

Question: Are you doing "AI" or "SI"? Answer: Neither. Be more precise about the exact concepts and tools being applied. You are using language models (large, medium, or small, to be quantified where possible), or you are using neural networks, etc. 1/4

The Trump administration tried to claim Big Bend was a "high activity" sector for border crossings, but evidence presented in court indicated it was dead last. It's a real shame that the government can no longer be trusted to give truthful testimony.

I thought this might be an exaggeration, but no! Despite all the talk of technology neutrality, it appears the permitting reform proposal would weaponize claims for federal damages — but in practice, only for fossil fuels.

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.

National Science Foundation Diverted $1.4 Billion in Science Funds Mandated by Congress (Gift Article)
The move, affecting about one-fifth of the National Science Foundation’s primary research budget, is the latest sign of how the White House is asserting more control over grants.
