I've been thinking about this recently. As a trans person with dual citizenship, the political climate is motivating me to get my paperwork together to be able to leave if worst comes to worst. Reminds me of my parents scrambling to get their US citizenships after Bush was elected... Ironic reversal

the latter must come from people confusing “intend” with “intent [on]”, right? these both annoy me so much 🙃

Sometime close to me was very sick with covid at the same time I was, Feb ‘23. Their doctors urged them back to work, saying the fatigue was all in their head. Now they are wheelchair- and home-bound. My partner knew the lit, insisted I rest for *2-3 months* — I’m now fully recovered.

Just FYI we’re entering a summer Covid wave right now (especially western regions in the US); you can see it in the CDC wastewater plot here (and anecdotally a bunch of my friends are suddenly testing positive). www.cdc.gov/nwss/rv/COVI...

This isn't quite right. There are a few hypotheses for the origins of "Istanbul", one of which is that emerged from the Greek phrase "in/to The City" which sounds somewhat similar — but it's not just "The City" in Greek, and there are other credible hypotheses for the name's origins too

The boards displaying flights in Greek airports — alternating a few seconds in Greek, a few in English — still flip between “Istanbul” and “Κωνσταντινούπολη” 😂

Wow. A restaurant in Chicago O’Hare, one of the biggest airports in the world, banned an infectious disease doctor from entering because they were wearing a mask. This is unacceptable.

Gotta say, a major take-away from FAccT this year for me has sadly been the lack of masking. Lots of people in this community want to talk about radical, progressive approaches and uplifting marginalized groups, but don't back it up with actions 💔😷

Drawing a line between appropriate moderation and problematic censorship is challenging, both technically and normatively — a line we think is best navigated by humans. Pay professional writers! 

For more (there is so, so much more), see our paper: dl.acm.org/doi/10.1145/... (8/8)

So far, most attention has been paid to the risk of LLMs producing harmful or dangerous content. But our work suggests we should be attuned to another risk: that of censorship. In a world of LLM-generated cultural content, we should be asking: what stories won’t be told? (7/8)

In the course of our study, we were also able to empirically determine what genres of TV shows were most likely to flag (crime, drama, horror, and sci-fi), what flags were most likely to be raised (violence), and estimates of GPT’s numerical cutoffs for raising a flag. (6/8)

In addition to real scripts, we had GPT-3.5 & -4 generate scripts based on synopses from IMDb and Wikipedia. Compared to real scripts, these were less likely to flag, suggesting GPT is self-censoring, producing content that lacks many key themes of the actual TV episodes. (5/8)

We tested real scripts and found that GPT flagged ~70% of them as violating content.  OpenAI requires users to be 13+ to use the site - certainly TV-PG shows should be appropriate! But even just looking at shows rated TV-PG, many PG-rated real scripts were flagged too. (4/8)

ChatGPT isn’t just an LLM; it also has content moderation filters to keep users from seeing or generating hate speech, violent content, and other disturbing results. But as it turns out, popular TV shows often contain some violence, sex, and other too-colorful content. (2/8)

Can ChatGPT write your favorite TV show? Inspired by the Hollywood Writers' Strike, we set out to find out. But we immediately ran into a problem:

I hope this won’t be your experience, but when I used mine in response to my semi-fancy bike getting stolen in grad school I was initially thrilled — until the next year when State Farm wouldn’t let me renew and instead barred me from being insured by them 🙃

The part of the flow that can take days & explicitly involves TAPS staff is indeed human-in-the-loop, but the other flow I was battling is purportedly separate from that. What happened in your case, post-deadline??

Why am I debugging in a workflow that involves making changes in my single-column LaTeX while trying to mentally anticipate what will happen when TAPS transforms it into two-column, and then waiting 10-25 minutes to see the results?? Just give me a two-column template and skip all this madness!!
