Agentic AI Comes to Medicine

Posted on by

Following excerpt from Dr. Eric Topol’s Ground Truths:

“MIRA queried the patient’s history, the physical exam results, and could order labs, blood cultures, scans, medications, procedures, surgery, and triage for hospital admission. This was done in 500 emergency department established real cases with the MIRA results directly compared to 4 board-certified (BC) physicians, and also to a hybrid group of 2 BC physicians and 2 residents. […] The overall diagnostic accuracy for MIRA was 87.8% compared with BC physicians at 78.1%.” 

Railroad tie wheel chock

Posted on by

Not clearing as much brush these days and tend to rely on a big one in the woods behind the Annex. SOP is putting the pickup in 4WD and backing up to the pile. But the truck struggles to hold its position and threatens to roll down the hill. To prevent this I moved an ancient railroad tie into place as a wheel chock. (Note use of tie-down ratchet to get the thing into the truck)

“Do teens regret their social media use?”

Posted on by

The blogger in me is surprised and delighted by #3.

“So how did social media regrets hold up? Out of 20 possible regrets, too much time on social media ranked 13th. The top regrets were 1.) not sticking up for oneself, 2.) being too self-conscious, 3.) not documenting memories, 4.) not learning practical life skills and 5.) not getting help with mental health. Girls were slightly more likely to regret time on social media than boys.”

“We are talking to aliens now”

“We are talking to aliens now, just didn’t come to us the way we thought they would. I don’t think (the film) 2001 anticipated they would think in completely different ways from us, and would not understand the differences. They talk to us as if we were them, the same way your cat thinks you’re just a bigger cat.”

— Dave Winer

Perplexity provides the following analysis:

Winer’s metaphor is doing a few interesting things at once, and it’s sharper than it looks on first read. At the surface, “aliens” refers to AI systems—entities that are clearly intelligent in some sense, but whose internal structure and way of “thinking” are not human-like. The key claim isn’t just that they’re different, but that the difference is opaque in both directions. Continue reading →

Consciousness or Not

“The biggest benefit from language was not the ability to communicate with others but the ability to communicate with ourselves. Language allowed us access to our own minds. It gave us a way to manipulate our thoughts. To reflect, to operate on memories, to predict. It gave form to ideas.”

“In the next 25 years we’ll learn more about ourselves than in the last 25,000 years. One hundred years from now we will have a very different idea of what we think humans are.”

— Kevin Kelly

The “Godfather of AI” believes AI is already conscious.

Posted on by

Geoffrey Everest Hinton (born 6 December 1947) is a British-Canadian computer scientist, cognitive scientist, cognitive psychologist and Nobel Prize laureate known for his work on artificial neural networks, which earned him the title “the Godfather of AI”.[8] He is University Professor Emeritus at the University of Toronto.

In this interview, he discusses something he rarely says out loud: he believes AI is already conscious. Not eventually. Not theoretically. Already.

Dr. John Middleton

Posted on by

It was just a few months after I got my Land Rover that I met John Middleton. Someone told me he had a collection of Rovers so I tracked him down and he invited me up to Columbia. In the ensuing years John was an invaluable resource whenever my Land Rover had a problem. Even joined the crew to help me take the top off and on.

Today I took the hoop kit (I used for just one summer) up to John’s farm and to see some of his recent acquisitions. During my brief visit I mentioned the MU vet school where John is a professor. He said something about his duties changing since we last talked so when I got home I asked Perplexity what it could find.

The photo above is John Reeder (the news/farm director of KBOA in the 1950s) interviewing Elia Kazan during the filming of A Face in the Crowd in 1957. (more info here)

I think the first time I saw a reel-to-reel recorder like the one in the photo was when my dad brought one to my school for one of those What My Dad Does for a Living things. He set up the recorder and let everyone record a few words. Probably the first time most of us had ever heard a recording of our voice.

In another of my AI experiments, I uploaded the image to Gemini to see what it could tell me about the recorder. Continue reading →

Perplexity is a better writer than I

Posted on by

A couple of years ago I pulled together some notes and files about Learfield’s early adventures with the Internet. (I’ve posted on this topic more than once.) Yesterday it came up in a conversation with Perplexity which asked I would like to see a “narrative chapter” of that history. I was pretty sure Perplexity would produce something more readable so I said “go ahead.” 

It boiled my fourteen page ramble down to three pages while creating a story that –to my mind– accurately captured the vibe of those frantic days. [Links above to PDFs]

I’ve resisted the temptation to let an AI write or rewrite these blog posts and will continue to do so. But I wonder if it’s much different than an author submitting a manuscript to an editor who cleans it up and generally improves it.
