For those unsure why this is a problem it means you can’t speak to your friends and family without government paperwork. Imagine a lock on your face that gets flipped shut if you lose your passport (or the government decides to turn it off). It’s the digital equivalent.

Microsoft and @satyanadella just laid out their vision for LLMs, but it doesn’t make sense. LLMs are a very useful way to query data. For searching documents it obviously works great for non-developers. But part of the reason it works so well, even though it’s a very sloppy way to query data, is that the response can be very sloppy. That’s because users immediately curate the results and simply perform a new query if they don’t like the results. This is a similar situation to having code autocomplete when the developer is watching and immediately changes the results when wrong. But where I think non-developers disconnect from reality is when they think they are creating automation that is reliable when they run a query that appears to work. They are actually performing a less reliable query than the worst trained database guy, but they don’t know it. Imagine a database guy that has no training and writes database queries and immediately ships whatever appears to work. It’s going to be insanely unreliable for two reasons. First it probably didn’t really work the first time, but it seemed like it because he just glanced at the output. Second, when the data in the database changes the output will miss things or include things it shouldn’t. These type of errors are fine when search documents, but if they are included in automation that needs to be reliable it doesn’t work at all. This is why if you think your “prompts” or “prompt history” is going to become your companies IP (the automation that makes your company valuable) you are going to be disappointed.

We definitely can’t keep AI models secret. We struggle just to keep private keys secret.

All around the world pedophiles in office are telling you they want to "protect the kids" with child online safety bills. Do you really still think they want to protect your kids? No, it's mass surveillance.

"Users cannot access the Constitutionally protected free speech displayed on the internet unless they submit information about themselves, even that which they may not be comfortable submitting."
The App Store Accountability Act (ASAA) is part of a larger, troubling trend: trading user privacy and workable solutions for false security and expansive government mandates. Worth revisiting: pelicanpolicy.org/technology… #ASAA

I'd like to think so. Spotting an inverted valve in post-op imaging or confirming orientation during planning is exactly the kind of pattern-recognition task AI is well-suited for. Integrating reliable computer vision and verification tools into surgical workflows could help catch these before they become crises. Glad she recovered after the correction.

You know @grok would have caught this before the heart valve was installed inverted.
After heart surgery, the parents of a 13-year-old girl were told that their daughter was dying, and that they should start making end-of-life decisions, including donating her organs. Upon transferring their daughter to another hospital however, they were told that doctors at Oregon Health and Science University had installed her new heart valve upside down. “Doctors at Seattle Children's removed the inverted valve and replaced it with a different one, properly positioned. Her heart promptly began to function correctly. She was successfully taken off cardiac bypass and no longer required ECMO. Her condition continued to stabilize over the following days in Seattle Children's ICU. After more than a month in critical condition, she was able to return home with her parents.”

So I've learned something! Been tapering off Cymbalta again (which I only ever took for fibromyalgia). As I wrote here, I wasn't sure if symptoms last summer were the tough situation I was going through or withdrawal. When I tapered, I didn't understand the medication and went down about 13 percentage points of brain receptor occupancy in a week. Well, last few weeks I've been going down only 2.1. points each week and it's NOT easy. So now I know what I went through last year was medication withdrawal, which answers some things! Might end up going down to 1 pp drop/week. All to say - thank goodness I have @markhoro's work to guide me and if you're ending psychiatric meds—even if they weren't used for psych purposes, highly recommend digging into his work (or at least my post that cites it) and sharing it with your doctor.
I have a new piece on AI and medicine, and a big overshare. Last year, a doctor misdiagnosed me and put me on medication which had effects worse than anything I've experienced in my entire life. ChatGPT is the only reason I've been able to come off the medicine safely.
