This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.
Jump in the discussion.

Notes -
A radiologist friend of mine was pretty gungho on AI when ChatGPT came out, but he's pretty rapidly soured on it and is motivated to want a lot more regulation of that sort. People have been talking about automating away radiologists for decades at this point, but This Time is Different. Really.
I have little doubt that it is technologically possible to train an AI to make most major radiological diagnosis with average or above-average accuracy. The main obstacle is medical privacy laws restricting the data. HIPAA may be the most destructive statute ever enacted by the United States congress. The fact that it passed the senate 100-0 is perhaps the greatest indictment against democracy that exists.
Buried in this statement is the assumption that only the United States is capable of performing cutting edge medical research.

I think that’s a bit much. The intent of the law was to prevent things like your medical records being used against you at work. Like you have a genetic risk for a disease and thus become effectively unemployable because your medical history or genetic data would put you in a high risk pool that would make your boss’s insurance rates go up. And had it been properly written, I don’t think it would be a problem for AI radiology at all.

I am not claiming that ChatGPT 3.5, which was the SOTA at the time of release and what he almost certainly used, is better than most doctors. I would say it's surprisingly good, about on par with a bright med student in say their third year, which is still plenty useful.
I have on the other hand, become well acquainted with GPT-4, which is where I make that case. Leaving aside my subjective impression, not only did it pass the USMLE, it did so with a 95th percentile score. That's not just a begrudging pass, it's stunning.
Given that the whole point of the USMLE is to comprehensively test the capabilities of a doctor, while also gating entry into residencies, I struggle to see how that isn't overwhelming evidence in its favor. If I sat the USMLE right now, even fresh as I am from an equivalent UK examination with an even lower pass rate, I couldn't do that, and if I could, it would represent at least half a year of constant studying. Since I and tens of thousands of others who aren't 95th percentile are allowed to practise as is..
Further, while GPT-4 has multimodal capabilities, being able to look at image files and understand them, such capabilities are not currently publicly available. I struggle to see how a radiologist would be making proper use of it, let alone when they almost certainly used the older and weaker 3.5, since half their job is looking for weird blobs in an image and translating them to a legible diagnosis or at least a list of findings.
Yes. It is different this time, and we have receipts to show it. Besides, I'm not the same people who were claiming that would be the case as early as two decades ago, if only because I was too busy memorizing multiplication tables.
At least your friend is smart enough to ask for regulation, if only for the wrong reasons. I'd do the same, but only because it's convenient for me, not because I actually think it's worse at the job.
Oh, yes. To be explicit, the souring is out of his fear of its capabilities (rather, what it's clearly tracking toward), not contempt at a lack of them. He's shifted to questions about HIPAA and big tech companies controlling data, importance of bedside manner (hilarious if you knew him), etc.
