Getting some pushback. Right now, reviewing is an activity we do not even prioritize. We force people to do it, with no ~0 repercussions for doing a crappy job. No one gets tenure by reviewing well, or spending their time shooting down junk. Once we fix _that_, we will get useful peer review.

Too many times as a reviewer and as an AC have I had to deal with this. Your job is not just to handle your own review/response. You need to interact with other reviewers to come to a decision. In particular, if your review disagrees with everyone else, the burden is *on you* to engage.

"92 million low-income people in the U.S. states—everyone whose income is less than 200 percent of the federal poverty line—have some basic aspect of their lives decided by AI" www.techtonicjustice.org/reports/ines... this is a damning report
reads: The Ways AI Decides How Low-Income People Work, Live, Learn, and Survive

The use of artificial intelligence, or AI, by governments, landlords, employers, and other powerful private interests restricts the opportunities of low-income people in every basic aspect of life: at home, at work, in school, at government offices, and within families. AI technologies derive from a lineage of automation and algorithms that have been in use for decades with established patterns of harm to low-income communities. As such, now is a critical moment to take stock and correct course before AI of any level of technical sophistication becomes entrenched as a legitimate way to make key decisions about the people society marginalizes.

Employing a broad definition of AI, this report represents the first known effort to comprehensively explain and quantify the reach of AI-based decision-making among low-income people in the United States. It establishes that essentially all 92 million low-income people in the U.S. states—everyone whose income is less than 200 percent of the federal poverty line—have some basic aspect of their lives decided by AI.

I wrote a Part IV postscript to my job market blog post to add what I've learned as faculty. TL;DR: No one is out to get you. For anything not going your way, it's probably due to people being busy or bureaucracy. And there are probably people working very hard for you behind the scenes regardless.
