Journal 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).

Requests grew slowly from 3 (2012) to ~30/year (2019–2023), then jumped sharply after ChatGPT's release, hitting 86 in 2024 and 73–80 in 2025–2026.Bar chart of journal review requests per month, 2012–2026, with a smoothed trend line.

Your opportunity to comment on the proposed NSF Guidance on Financial Assistance ends next Monday, August 24. There are WAY fewer comments on this than the earlier proposed OMB government-wide regulation, but this rule codify's the SAME policies! Attached is my comment to NSF.

The 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. This blog post summarizes the results (full analysis linked in post). www.jhelvy.com/blog/2026-07...

OMB has proposed a sweeping rewrite of the rules that govern every federal grant. Thousands of people filed comments. I downloaded them to look at what they actually say.

Dissenting on a birthright citizenship case should be disqualifying for SCOTUS. Not only is the language of the 14th amendment abundantly clear, we fought a civil war to enshrine it in our constitution. That amendment was a very, very costly amendment. Shame on Alito, Gorsuch, and Thomas.

🚨 The U.S. scientific enterprise faces an existential threat few are talking about. A proposed OMB rule would reshape ALL federal research funding — NIH, NSF, DOE, DOD, every agency. What it does & how to push back 👇 defendfederalresearch.org 🧵...

Comment on the OMB Rule

The proposed OMB Regulation for Federal Financial Assistance would put political appointees over peer review and let agencies cancel active grants. Here’s what it changes and how to comment before Jul...

The 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 🤔

A line chart titled "BUILD America 250 proposed EV fee penalizes EV owners & is not justified by gas tax revenue loss." The x-axis shows Gas Vehicle Fuel Economy in MPG (10–55), and the y-axis shows Breakeven Annual Miles (0–35,000). Two upward-sloping lines show the annual miles an EV owner would need to drive to pay the same in gas tax as a comparable gas vehicle: one for the $130 initial fee and one for the $150 fee cap. A horizontal dashed line marks the average annual miles driven (11,484), and a vertical dashed line marks the average MPG (22.3). The region above the breakeven lines is shaded red and labeled "EV Fee > Gas Tax"; below is shaded green and labeled "Gas Tax > EV Fee." At average MPG and average miles, both breakeven lines fall well above the average driving line, indicating most EV owners would pay more under the proposed fee than a typical gas driver pays in gas tax.

A less extreme version is just to put speed governors on every car. You can put the cap at something like 85mph, but seriously beyond that there is truly no reason to be allowed to drive faster except like running from the cops

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area. (15 in Manhattan btw)

We are watching our democracy crumble. With this SCOTUS ruling, every state has no choice but to follow TX and redraw their voting maps. The south will become an entirely white R vote, and blue states will become entirely D. The changes made now will lock in polarization for a generation or more.
