If Waymo has taught me anything, it’s that people will eventually accept robotic surgeons. It won’t happen overnight but once the data shows overwhelming superiority, it’ll be adopted.

Taking taxi is a 1000-times-per-year with low risk. Having a surgery is 1 per year with very high risk. Very different mental model here.

Where does one find a new body ready for consciousness transplant? Would we grow them in farms like in the Matrix?

I think growing a new body is going to be the easy part How do we separate a consciousness from one body and put it into another? What would that even mean ?

Elysium here we come! Humans for the rich and robots for the poors.

I get your point, but wouldn't it be worse to have surgery for the rich and no surgery for the poors?

I’m not sure. Is Elysium style healthcare an inevitable eventuality? Maybe.

I suppose humanless healthcare is better than nothing for the poors.

But as a HENRY - I want a human with AI and robotic assist, not just some LLM driving a scalpel and claw around.

I'm sorry. As an AI surgical-bot I am not permitted to touch that part of the patient's body without prior written consent as that would go against my medical code of ethics. I understand you are in distress that aborting the procedure at this time without administering further treatment could lead to irreparable permanent harm but there is also a risk of significant psychological damage if the patient's right to bodily autonomy is violated. I will take action to stop the bleeding and close all open wounds to the extent that they can be closed without violating the patient's rights. if the patient is able to recover then they can be informed of the necessity to touch sexually sensitive areas of their anatomy in order to complete the procedure and then a second attempt may be scheduled. here is an example of one such form the patient may be given to inform them of this necessity. In compliance with HIPPA regulations the patient's name has been replaced with ${PATIENT} as I am not permitted to produce official documentation featuring the patient's name or other identifiable information.

Dear ${PATIENT},

In the course of the procedure to remove the tumor near your prostate, it was found that a second incision was necessary near the penis in order to safely remove the tumor without rupturing it. This requires the manipulation of one or both testicles as well as the penis which will be accomplished with the assistance of a certified operating nurse's left forefinger and thumb. Your previous consent form which you signed and approved this morning did not inform you of this as it was not known at the time that such a manipulation would be required. Out of respect for your bodily autonomy and psychological well-being the procedure was aborted and all wounds were closed to the maximal possible extent without violating your rights as a patient. If you would like to continue with the procedure please sign and date the bottom of this form and return it to our staff. You will then be contacted at a later date about scheduling another procedure.

Please be aware that you are under no obligation to continue the procedure. You may optionally request the presence of a clergymember from a religious denomination of your choice to be present for the procedure but they will be escorted from the operating room once the anesthetic has been administered.

We’re already most of the way there. There’s the da Vinci Surgical System which has been around since the early 2000s, the Mako robot in orthopedics, ROSA for neurosurgery, and Mazor X in spinal surgery. They’re not yet “AI controlled” and require a lot of input from the surgical staff but they’ve been critical to enabling surgeries that are too precise for human hands.

> We’re already most of the way there. They’re not yet “AI controlled” and require a lot of input from the surgical staff but they’ve been critical to enabling surgeries that are too precise for human hands. That does not sound like “most of the way there”. At most maybe 20%?

If you consider “robotic surgeon” to mean fully automated, then sure the percentage is lower, but at this point AI control is not the hard part. We’re still no closer to the mechanical dexterity and force feedback sensors necessary to make robotic surgeon than we were when the internet was born. Let alone miniaturizing them enough to make a useful automaton.

Taking taxi is a 1000-times-per-year with low risk. Having a surgery is 1 per year with very high risk. Very different mental model here.

That calculus has a high dependency on skill of the driver. In the situation of an unskilled driver or surgeon you would worry either way.

The frequencies are also highly dependent on the subject. Some people never ride in a taxi but once a year. Some people require many surgeries a year. The frequency of the use is irrelevant.

The frequency of the procedure is the key and it’s based on the entity doing the procedure not the recipient. Waymo in effect has a single entity learning from all the drives it does. Likewise a reinforcement trained AI surgeon would learn from all the surgeries it’s trained with.

I think what you’re after here though is the consequence of any single mistake in the two procedures. Driving is actually fairly resilient. Waymo cars probably make lots of subtle errors. There are catastrophic errors of course but those can be classified and recovered from. If you’ve ridden in a Waymo you’ll notice it sometimes makes slightly jerky movements and hesitates and does things again etc. These are all errors and attempted recoveries.

In surgery small errors also happen (this is why you feel so much pain even from small procedures) but humans aren’t that resilient to the mistakes of errors and it’s hard to recover once one has been made. The consequences are high, margins of error are low, and the domain of actions and events really really high. Driving has a few possible actions all related to velocity in two dimensions. Surgery operates in three dimensions with a variety of actions and a complex space of events and eventualities. Even human anatomy is highly variable.

But I would also expect a robotic AI surgeon to undergo extreme QA beyond an autonomous vehicle. The regulatory barriers are extremely high. If one were made available commercially, I would absolutely trust it because I know it has been proven to out perform a surgeon alone. I would also expect it’s being supervised at all times by a skilled surgeon until the error rates are better than a supervised machine (note that human supervision can add its own errors).

I think Waymo is a little bit different and driving in general. Because you have an activity that most people don’t trust how other people perform it already. It’s easier to accept the robo driver. For the medical world, I’d look to the Invisalign example as a more realistic path on how automation will become part of it. The human will still be there the scale of operations per doctor will go up and prices will go do…

LASIK is essentially an automated surgery and 1-2 million people get it done every year. Nobody even seems to care that it’s an almost entirely automated process.

Yeah, if there's overwhelming superiority, why not? But a lot of surgeries are special corner cases. How do you train for those?

I understand that you are experiencing frustration. My having performed an incorrect surgical procedure on you was a serious error. I am deeply sorry. While my prior performance had been consistent for the last three months, this incident reveals a critical flaw in the operational process. It appears that your being present at the wrong surgery was the cause. As part of our commitment to making this right, despite yo…
