John Paul Helveston @jhelvy.bsky.social · 03/09/2026Journal editors can't find reviewers because we're overwhelmed. I checked my gmail, review requests have more than doubled since the pre-LLM days. This is also why you're seeing more AI-generated reviews - reviewers can't keep up and reach for the LLM to get the job done faster (not better). 060

John Paul Helveston @jhelvy.bsky.social · 18/07/2026The public overwhelmingly rejects OMB's federal grant rule change. I used the GPT 4o mini LLM to classify the comments, showing 94% in opposition. Of the 5% supporting, ~84% are verbatim copies.

John Paul Helveston @jhelvy.bsky.social · 14/07/2026There are 496,769 comments on the OMB rule that will devastate U.S. science.

John Paul Helveston @jhelvy.bsky.social · 02/06/2026The BUILD America 250 Act charges #EV owners $130/year to "pay their fair share" in road taxes. Hogwash. Average drivers pay ~$95/yr in federal gas tax. A 50 mpg hybrid pays just $42, yet no surcharge for them. It's almost like this has nothing to do with tax revenue and is just an EV penalty 🤔 5318

John Paul Helveston @jhelvy.bsky.social · 13/05/2026#Quarto is much more than a publishing framework. When leveraged with agents with Claude code, it's a powerhouse tool for agentic workflows.

John Paul Helveston @jhelvy.bsky.social · 30/04/2026We are watching our democracy crumble. With this SCOTUS ruling, every state has no choice but to follow TX and redraw their voting maps.
