Cutest use of chatgpt I've seen yet: husband used it to write a tailored read-your-own-adventure for the boys with their own names and story elements they like Both 5-year-old and 7-year-old were absolutely rapt + excited

@TheLizVariant VHS tapes are cheap. You can buy a movie for much less than the “buy” option on Amazon Prime at a thrift store or rummage sale with VHS and DVD shelves.

There’s a growing trend of parents intentionally raising their kids like it’s the late 90s again. No iPads. No algorithm. Just bikes, VHS tapes, books, outside play, family dinners, and boredom that forces kids to actually use their imagination. Id love to know where they’re getting these VHS tapes?

This is how we're raising our kids. No tablets, no smartphones until high school, lots of time outdoors. But we will revive the 90s desk area for our children. It will be a shrine through which they learn the Internet.

Do LLMs possess coherent utility functions? We mapped the preferences of Llama-3.1 over risky portfolios. A positive logit difference (blue) indicates that the model picked that portfolio over the reference (yellow star) in a binary choice scenario. The resulting indifference contour (black) closely tracks a standard Mean-Variance structural model (yellow dashed line).

@jennfrey This week I volunteered to run dodgeball at Field Day, because that worked for me. I could handle it without dropping other important things. At other times, doing the dress up day, especially for a preschooler(!), did not pass the cost benefit test and got entirely skipped.

@AlecStapp Do you have any grid for thinking about job security in this world? If someone talented really wants to do this but is tempted by the stability of government work, what would you tell them?

@MrRBourne This is why first time parents really need to run the numbers on paying for child care vs the Mom staying home. They need to factor in the household federal and state marginal tax rates, FICA, the direct costs of working like commuting/clothes/food, and then subtract daycare.

@dramadork884 @jennfrey Life is full of trade offs. Some days we don’t meet everyone’s (anyone’s) expectations. Still glad I have my kid. Some families can easily accommodate dress up days and some cannot.

@aboutJoy @jennfrey So kids get left out? And helping your kids dress up is fun why would you want to skip out of the fun parts of parenthood?

@queengrowlithe @jennfrey It can be great fun for people who WANT to do it. And older kids might be able to take on the mental load themselves.

@aboutJoy @jennfrey yep. we do them for our countdown to the end of the year and some kids participate and some kids don’t (except pajama day, they all love that one 😂). no one has ever given anyone grief about not dressing up.

@lymanstoneky Thought: what if people start liking each other enough to want to marry each other because of GLP1s? When do you think there would be enough data to test that?

@kn_owled_ge Handing something in by the deadline is a skill that is still being tested in 2026. (Maybe not for long if they set up an agent…)

Teaching in the age of LLMs: I failed 4 students, for the first time ever. I also gave more A+'s than ever before. In previous years, students realized after the first or second HW that they weren't in Kansas anymore and needed to work hard. No more. Just solve it with LLMs. But then the midterm arrives, and they can answer 0 of 40 questions. Do they reform their ways? Nah, they just decide to "give up" on class, assuming they'll get a B, or a C, or whatever, because they submitted HW and got decent grades on those. And never before have they encountered a professor who will dare fail them. The flip side is that the most "agentic" students now have the world's best tutor at their disposal. They deeply understand the material and aced my (intentionally very difficult) exams. As if we live in "The Diamond Age". Inequality galore. From my vantage point, "the permanent underclass" appears to be about agency, not assets.

There are important distinctions getting blurred in the conversation about arXiv and generative AI. arXiv’s written policy does not prohibit LLM use (see attached). In fact, it directly acknowledges that authors may use these tools, while emphasizing that authors remain fully responsible for the entire submission. But, the recent X thread on enforcement raises deeper questions and seems to mingle evidence of LLM usage with more severe misconduct. What counts as evidence of misconduct versus evidence of imperfect editing using tools that are explicitly allowed? If a manuscript contains hallucinated references, fabricated claims, invented data, or misleading content, that is a serious problem. Such authors have failed in their responsibility, regardless of whether the source was an LLM or not and deserve penalties. But if a paper contains a leftover drafting comment from an LLM - or a stray human comment judged as similar to an LLM, e.g., to a postdoc "Please add the newest data here in a short paragraph" - that also seems to meet criteria for the proposed bans. I feel that treating every visible AI artifact as evidence that the entire paper is untrustworthy risks overshooting the balance between allowing AI slop to run wild and curating impactful research. This is a very tough balance to define, and ArXiv is ground zero for many of these changes and they have done a noble job trying to figure things out. But, circling back to the beginning, this blurring is especially confusing as official arXiv policy says that generative AI use is allowed. If that is the policy, then the presence of some sign of AI-assisted drafting should not be considered the core violation. In my opinion, a more durable standard would separate things like minor drafting artiacts, or sloppy manuscript preparation from the much worse problems of hallucinated references, or worst of all - fabricated claims, figures, or data. I want to conclude by saying thank you to arXiv for their brilliant work as a whole; they are a foundational capability that has allowed AI and science across the board to flourish. But, there is work to be done on this policy. Also, can we please write this into an official arXiv policy instead of trying to infer from Prof. Dietterich's X post alone? :)

People are trying to figure out a new equilibrium for paper production and sharing. The ban is harsh but the alternative might be that these websites become unusable from slop invasion. What norms should we adopt?
Luca Ambrogioni@LucaAmb

@aboutJoy @notadampaul they seem to imply that any evidence of any sloppiness in LLM use at any point of a paper is serious enough, even when the paper itself is high quality
