Infrared spectroscopy, HPLC, Surface-enhanced Raman spectroscopy, and reverse ecology are examples. Figuring out the purity of one's foods/drugs (which is not done enough) can be a Pareto-efficient improvement on the attention economy of "pivotal actors", and can be done by environmental health specialists (whose skills are orthogonal to "pivotal actors"/those...
Water quality can have surprisingly high impact on QoL (just as air purifiers can significantly improve QoL), and some steps (like getting the right pitcher have very high return on time/attention invested). There still isn't a LW thread on water quality so I'll post it here. Water may contain disinfection...
Eg a LLM like GPT4/GPT5 (they don't seem to capture all of it yet)? Would it capture all shortform posts and shortform questions? If I want to reliably surface some rare content, would LW be of the best places to surface it? And which LLM would it most likely come...
(aka the vast majority of people in the world). I know that many of them can still benefit from those who are in support roles for them. The speed at which top AI researchers need to learn new AI content is.. just.. extraordinary even by the standards of any other...
