My gut as a physician says AI will revolutionize primary care the most and the premise of AI having more specialized knowledge than a PCP holds water - I think the future of primary care is AI equipped midlevel providers - so I was very exc

Probably cheaper and substantially better contrast resolution to use low field strength perma magnet MRIs with advanced computation to be honest.

This is ridiculously optimistic. The technology, USCT with full waveform inversion, is not new. It’s already used in breast imaging (SoftVue) and hasn’t replace mammography. A body part ideally suited for ultrasound. More compute many minim

There is some evidence for hormesis - but yes no model is proven right now. LNT is the most conservative model and part of why it sticks around. A good primer: https://pmc.ncbi.nlm.nih.gov/articles/PMC2477686/

You’re loosely alluding to personalized medicine but envisioning is a very futuristic state we are very slowly moving towards. What you suggest is great but we are a few decades and several technological breakthroughs as well as new discove

You’re assuming a diagnostic test can be designed for 100% accuracy and this is not possible as disease states are spectrums not discrete categories. “Normal ranges” in lab values are just confidence intervals of population means which by d

The better question is are there any sources that AI is better than human readers? I haven’t heard anyone make this claim outside of single/few disease classification tasks and even those are mostly 2D. Anecdotally, my practice has mos

Whenever it comes to medical diagnosis I would caution anyone to be careful with what “beat humans” really means. In real life pathology is a spectrum not a binary and physicians are not trained to be 100% accurate instead optimizing sensit

I don’t think so, not beyond the current trend in medicine which is going up anyway. For some things, like 3D volume segmentation of structure or disease (e.g. CVA/stroke volume, cardiac muscle mass, iron quantification) the bottleneck

It’s actually quite a lot worse than even doctors in training except for highly constrained experimental settings and a few very nice applications that are mostly too tedious/impractical for a human to do or are very basic detection ta

The upper bound is limited by market size and cost of intelligence. Throwing more intelligence at a problem doesn’t necessarily pan out financially otherwise we wouldn’t have single underemployed biology PhD.

You’re putting the cart before the horse - alignment is an unsolved challenge (there are proposed approaches and active research on this) but it is still not established (beyond theory) that latent reasoning is more capable than CoT on hard

“a bunch of people” aren’t what caused the virus to become less severe. Y2K was overblown how it was portrayed by the media but is irrelevant to the analogy of unsubstantiated extrapolation of early exponential growth.

by haldujai 4mo ago
I think you’re overstating the impact of interpretability here. Your earlier point that latent reasoning models can’t be trained very well and that discretization may be load bearing rather than a readability tax in addition to significant

I’m also reminded by the early COVID days when exponential growth was leading to predictions of the collapse of modern civilization and a billion dead, now it’s just another endemic respiratory virus.

The bigger gap is for healthcare and business operations which is very broad and includes datasets for AI training as one example.

I wonder if in your case (which is very common) the issue is a mismatch between expectations and reality. The medical system as we know is not designed for someone to listen to you and do a back and forth for hours. If we did that we would

Yes that’s what I meant too. Acquiring the images is the hard part in obstetrical ultrasound, reporting is very mechanical for the most part and lends itself well to AI.

Potential harm is always the same - misdiagnosis and/or mismanagement. It’s probably very low in the context of CGM and diabetes as the potentially harmful treatments require prescriptions. Device prescription requirements are usually
