Earlier quoted context omitted.

Name some other groundbreaking medical equipment that was brought about by VC funding, please.

da Vinci Surgical System, Zio Patch cardiac monitor, Butterfly iQ handheld ultrasound, Swoop portable MRI, Shockwave Intravascular Lithotripsy, CardioMEMS HF System, Tablo Hemodialysis System, MONARCH robotic bronchoscopy platform, Mako robotic-arm orthopedic surgery system.

Thank you for dealing with yet another midwit.

2 things: 1. We should absolutely pursuing these kind of ideas but given then nature of technological progress and our history with “democratization” things are likely to get worse before we get better. Matt is hedging a lot here reflecting this. 2. Maybe all this stuff is as promising as the various threads suggest but it’s bizzare that this is all being argued in culture war terms (you vs the gatekeepers) and not l…

Buried in tlb's response might be the J-curve, the S-Curve (=integral of J-Curve), the hype curve, and finally Braess/Jevon/Baumol: why is healthcare inflationary if it is so helpful and so needed. The tension between helpfulness and perceived necessity must be explored, ceterum censeo (3.)

I'm not a doctor but (Isn't there always a but after someone saying they aren't a doctor?) it seems to me we need three things to bring in a true revolution:

- imaging that can get down to the cellular level easily and often.

- the ability to process that imaging data to find issues effectively.

- the ability to act on that data in a minimally invasive way.

This is a step in the right direction for one and two and the third has had progress too by others. We aren't there yet, but I can see a future where individual cells are treated and at that point all sorts of things are possible.

actually i think the chatbot you consulted listed a bunch of stuff that is a pretty bad example of VC (deep capital markets) leading biotech innovation. Shockwave is a good example - HistoSonics is a much better example and was written about on HN. By comparison Intuitive has conclusively discovered that outcomes are more or less the same as non-teleoperated laparoscopic procedures, at least ones common enough to do a comparison.

Thanks to the Zio patch I was finally able to convince doctors I actually had a heart condition that I had been telling them I had for years. For about a decade they were telling me my irregular rhythm was due to anxiety.

I accept this (well-used) perspective from a practical, current perspective, but not for abstract diagnostics generally. From the Bayes' theorem, and same logic you use in Kalman filters: More knowledge, if you have data on the confidence, always helps. It only causes these negative outcomes due to acting poorly with the data (e.g. due to emotions and liability concerns, I suspect here)

I wonder how much of the knee-jerk cynicism comes down to it being Midjourney doing this in a way where it feels like "practicing medicine without a license."

The irony is I believe that if a medical devices company announced this, it was being sold to hospitals, and it would only cost the patient's insurance $100 a scan, then the medical industry would universally praise this as a breakthrough.

It is very easy to be cynical about change...especially in areas we are knowledgable...because all we see are the challenges.

And there will be lots of challenges with this. For my part, I'm not wild about what Midjourney might be allowed to do with this data. However, dealing with those problems seems better to me than leaving things as they are. This X post is a great example of "yes, and" instead of "no."

The most practical Bayesian counter (indep of matters of confidence) might be the info bottleneck:

  to generalize accurately, one must forget (irrelevant) details 
The risk (bottleneck) is in throwing out the relevant details
