I’ve long been skeptical about the business case for LLMs and generative AI. But Ed Zitron says AI companies inherent money losers.
And absent some improbable breakthroughs including solving the hallucination problem, that won’t improve.

Government word search is killing my cutting-edge research
The Trump administration seems to believe that some words and ideas fail an ill-posed and completely nonscientific test of orthodoxy.

Just received $48 settlement check in "Peters v Apple" class action case. My experience with minor class actions is that few people apply, and the $ payout is therefore larger than anticipated. (We got $300 from a minor Pet Smart #classaction Most much less.) Not always worth your time of course.

This is wild. Using LLM + a structural equation approach to both define and execute social science experiments. Theoretically it could work, but it depends how much knowledge about human behavior is in the LLM.

Gary Marcus: The explosive improvement in LLMs may already be ending. And so far, we have little idea how to fix their errors, except brute force.
Another case where empirical tech improvement wo. theory foundation = limited. Sad but plausible.

Evidence that LLMs are reaching a point of diminishing returns - and what that might mean
The conventional wisdom, well captured recently by Ethan Mollick, is that LLMs are advancing exponentially. A few days ago, in very popular blog post, Mollick claimed that “the current best estimates ...

Interesting argument that strategic air power, the subject of heated debate for decades, is active in Ukraine war — even though few aircraft are involved. Cruise missiles + drones do the same thing, at least for short ranges from Ukraine -Russia.
