“RTMH: Pope Leo’s Magnifica Humanitas on AI” by Zvi

His holiness has spoken, frequently about AI. At eighty two pages of length. The full Magnifica Humanitas can be found here. I am very happy that Pope Leo takes these issues seriously, and is sharing his views, and bringing a form of moral clarity, even with all the flaws and central errors. More people with voice should share their views in this way, even when I disagree. It's a weird document. Much of it is not about AI at all. I do agree with the Pope's most basic point on AI, which is that AI can be what we make of it. That we can steer this technology, determine how it is developed and used, and this can determine whether we get a good or not so good future. We cannot purely leave this to market incentives and strategic pressures. Yes, very much so. The central problem is that so much of Leo's worldview is some combination, to me, of highly alien and highly wrong. You might think that would primarily have a lot to do with him being the Pope and rather Catholic, and being a man of faith, whereas I am not [...] --- Outline: (03:02) A Brief History of Magnifica Humanitas (12:23) Economic Models Very Different From Our Own (14:14) A New Jerusalem (16:46) So Sayeth The Pope (on AI) (31:30) The Case Against Human Achievement (34:01) Truth, Justice and the Vatican Way (36:42) They Took Our Jobs (41:07) What Is Not Fair In Love and War (47:02) Come Ye Christian Faithful (49:13) The Other Missing Mood (51:42) Pope Given About Five Words (55:10) 0The Anthropic Principle (57:20) Claude Can Read Your Code --- First published: May 26th, 2026 Source: https://www.lesswrong.com/posts/RZeg98Tdrq47vbjva/rtmh-pope-leo-s-magnifica-humanitas-on-ai [https://www.lesswrong.com/posts/RZeg98Tdrq47vbjva/rtmh-pope-leo-s-magnifica-humanitas-on-ai?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration] --- Narrated by TYPE III AUDIO [https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration].

“Gemini 3.5 Flash Looks Good For How Fast It Is” by Zvi

Google once again has a model worth at least some consideration. Gemini 3.5 Flash is likely the best model out there at its particular speed point, as long as you don’t mind that it is a Gemini model. So for cases where speed kills, this can be a reasonable choice. Otherwise, I don’t see signs you would want to use it over Opus 4.7 or GPT-5.5. Google also had some other offerings for I/O Day, which this post will also cover. Introducing Google Gemini 3.5 ‘Flash’ Google introduced Gemini 3.5 Flash, which it seems is for now their universal model until 3.5 Pro comes along. It is live in the usual places. It is a hybrid, where it has the speed of Flash but the cost is at least halfway to models like Opus and GPT-5.5. Gemini 3.5 Pro is confirmed for next month. They are focused on 3.5 Flash as a daily driver for agentic tasks. It has the advantage of being faster and cheaper than Claude Opus 4.7 or GPT-5.5, if it can do the job. Not as cheap as previous Flash models, though, this is basically a hybrid: As always [...] --- Outline: (00:40) Introducing Google Gemini 3.5 'Flash' (04:52) Other People's Benchmarks (06:04) Reactions (12:18) Google AI Search (13:15) Google Daily Brief (14:21) Google I/O Day --- First published: May 22nd, 2026 Source: https://www.lesswrong.com/posts/WMZpPxqWEkZBBcaxf/gemini-3-5-flash-looks-good-for-how-fast-it-is [https://www.lesswrong.com/posts/WMZpPxqWEkZBBcaxf/gemini-3-5-flash-looks-good-for-how-fast-it-is?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration] --- Narrated by TYPE III AUDIO [https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration]. --- Images from the article: Pricing display showing input at $1.50 per 1M, output at $9 per 1M.

“AI #169: New Knowledge” by Zvi

Even in a relatively quiet period, AI is out there creating new knowledge. The new knowledge in question is OpenAI getting us the first truly impressive math result that comes from an AI, a solution to the unit distance problem. We’re about to learn a different kind of knowledge later today when the White House issues its executive order, or when the judges rule in Anthropic's DC case. And then there's the other kind of new knowledge, which is the knowledge that things are fake slop, such as a particular formerly supposedly prestigious literary prize. Meanwhile, METR issued a risk report on frontier models, concluding that they don’t yet have the means, motive and opportunity to cause the big issues, but that this would not obviously last so much longer. Andrej Karpathy has joined Anthropic, explicitly to do recursive self-improvement. He plans to later return to his education work, but if he succeeds at his new task there might not be anything left to return to. Congratulations to both sides, but also yikes. Elon Musk's case against OpenAI has been dismissed, because he waited too long. Table of Contents 1.

“Childhood And Education #19: Letting Kids Be Kids #2” by Zvi

I cannot emphasize enough the need to let kids be kids. In Childhood and Education #16: Letting Kids be Kids, I went over exactly how insane we have gotten about destroying the lives of children and along with them the lives of parents and others forced to devote endless hours to actively destructive supervision. I’ll go over a refresher of that, some related new anecdotes, and then some other related questions. People Don’t Let Kids Do Things As a refresher, here are some quotes and statistics from last time, because I really do think exposure to this type of thing needs to involve spaced repetition to sink in: 1. A third of people, both parents and non-parents, responded in a survey that it is not appropriate to leave a 13 year old at home for an hour or two, as opposed to when we used to be 11 year olds babysitting for other neighborhood kids. 2. A third of people said in that same survey that if a 10-year-old is allowed to play alone in the park, there needs to be an investigation by CPS.

“Housing Roundup #15: The War Against Renters” by Zvi

So many are under the strange belief that there is something terrible about not owning the house in which you live. So we massively subsidize home ownership, and try to actively interfere with renting. Except when we do rent control, which turns renting into a form of owning, and allows us to take real property and de facto give it to current renters. A lot of this is pure attempts to punish and exclude the poor. If you can’t afford a downpayment, we don’t want you living here. Go away. Some of it is the belief that when you rent, you are being ‘taken advantage of’ and that such a deal could not possibly be fair. Some of it is that if you don’t own, you don’t have the incentive to drive up property values. Which means you won’t properly work to ‘improve’ your local area, especially that you won’t conspire to block housing. The result of this is that if you’re not willing to commit to living in one place for years, or you can’t afford a down payment, you get punished, and punished hard.
