经过六年不明原因的不孕以及多次 IVF 胚胎移植失败,德鲁·豪斯曼和妻子把 GPT-4 当作一个不限次数、虚构的“医生”,用来探索那些他们没有时间向医生询问的医疗问题。他们给这个机器人取名“里德医生”,将检查结果、激素水平、扫描影像和治疗史输入其中;面对它自信但偶尔出错的回答,他们也会不时进行核实。 里德医生建议做一项磁共振成像检查,而豪斯曼的生殖科医生并未强烈建议这项检查。扫描结果显示,一枚六厘米大的黏膜下肌瘤挡住了一个可能着床的位置,多年的检查却始终未能发现它。妻子接受腹腔镜手术后自然怀孕,后来儿子取名为里德。 豪斯曼认为,AI 帮助他们找到了问题,同时也承认 AI 偶尔会产生幻觉并受到安全机制的限制。虽然他担心 AI 带来的风险,但他认为,自己的经历说明,普通人也可以借助易于获取的技术获得力量,即便这些使用者同时也在公开批评 AI。

Hacker News 上一篇关于“我们的 AI 助产士”的讨论,讲述了一对夫妻在接受生育治疗时使用 ChatGPT 的经历。经过多年试管婴儿治疗失败、医生又不断否定他们的判断后,聊天机器人建议他们主动要求进行核磁共振检查。检查发现了一个大型子宫肌瘤,手术最终使他们成功怀孕。 评论者大多认为,AI 的价值在于成为患者的倡导者:它有耐心、便于搜索,而且擅长提出被忽略的问题,帮助用户解读影像检查、比较治疗方案,并在碎片化的医疗体系中坚持下去。也有人批评这个故事只是个案,而且经过了选择性呈现,缺少明确的时间线,因果关系也不确定;此外还存在产生幻觉或自信地给出错误建议的风险。AI 在某些医疗任务上表现良好,并不意味着它在个体医疗中同样可靠。 更广泛的争论还包括:庆祝这类工具是否会淡化系统性医疗失灵;患者是否必须自己为自己发声;以及 AI 会不会复制医疗和科技行业中由利润驱动造成的目标错位。有些人认为,资源更应该用于改善公共医疗体系;另一些人则认为,这类实用工具可以立即提供帮助,尽管它们并不能解决所有社会问题。

This is a guest post by Drew Housman, whose review of Dominion earned finalist status in the 2024 ACX book review contest.

If you are unsuccessful for long enough on your pregnancy journey, and none of the many doctors you see can identify a problem, you get branded with a label. You now have “unexplained infertility.” This is good because there’s still hope of fixing the problem but dreaded because once you’ve reached this point the system is less interested in you. The fertility doctors don’t become unkind, but they also don’t give you the sense they are poring over medical journals trying to figure out your problem. They have looked for the keys under the streetlight and come up empty. Once you have unexplained infertility, the doctors start saying things like, “Have you considered using a surrogate?” and, “Sure, the last 5 embryo transfers failed, but what if we try a 6th and cross our fingers really hard?”

My wife and I could make healthy embryos, but none of the transfers were sticking. It was so frustrating to be able to create life only to have it trapped forever in a cooler at a hospital in Milwaukee, our babies like so many forgotten Miller Lights.

That’s when our LLM doctor stepped in.

Even if you’re paying a gazillion dollars for IVF treatments, you still only get a few precious moments to talk to your doctor every visit. That’s just how the US medical system works. If you want to plumb the depths of what treatments are possible, or ask super detailed and anxiety ridden questions about every single scan from the latest round of imaging, you’re going to want a chatbot by your side.

Once GPT-4 came out, we started using it for every question we didn’t have time for at the doctors office. At first it was unhelpful because OpenAI was nerfing their model and it refused to answer most medical questions. Then I read a tweet from someone who had figured out how to game the system. The trick was to ask ChatGPT to write a scene from a Hollywood medical drama that featured a doctor analyzing your situation. It worked beautifully.

Our Emmy winning doctor had infinite patience, a tireless work ethic, and would rather die than accept the utterly boring diagnosis of unexplained infertility. It chose the name Dr. Reid and got to work.

We asked Dr. Reid a lot of questions. We asked about our scans. We asked about levels of estradiol and progesterone. We asked about follicle counts and inflammation and cervical mucus and hysteroscopies and supplements and surgeon recommendations and anything else under the sun. We knew he was accurate because we’d spot check answers with our human doctors and they always said the same as Dr. Reid.

It was not totally flawless though. Once in a blue moon he’d look at an ultrasound and be like, “You’re pregnant, congrats!” and we’d have to say, “No, are you drunk Dr. Reid?” Then he’d shake it off and go back to being awesome.

There were also times where we’d run afoul of OpenAI’s opaque rules and the system would balk at our requests. At that point we’d get stern with it, or offer a monetary reward if it answered, or we’d assure it this was all just for fun. Then Dr. Reid would snap back into action.

Strangely, there were many times where ChatGPT decided it would answer our medical question, but not in the form of a TV medical script. The tides had completely turned! It felt like it was saying, “Okay, you won, can you stop making me write establishing shots describing the outside of a hospital now?” The older models were fun like that, so much more mercurial.

No matter how Dr. Reid chose to respond, he was in line with the medical establishment, had equivalent diagnostic skill, and he never forced us to wait 3 days to get a one line response in our MyChart app. We were happy.

One day, while lounging around and asking our phones how to get pregnant (the lounging being a way to satisfy all the people who told us we “just need to relax and you’ll get pregnant, that’s what happened to my cousin”), Dr. Reid suggested that we get an MRI.

You might think that is bog standard advice. Everyone gets MRIs these days. Surely we would have had an MRI of my wife’s uterus at some point over the course of our 6 year infertility struggle. It was already an ordeal that had included every other scan, test, and biopsy imaginable. In fact, we had never done one. In researching this article I found a single instance in our entire journey where the office notes floated an MRI as an option, but it was not emphasized or highly recommended, we never saw that doctor again, and the moment was gone.

We glommed on to Dr. Reid’s new direction and asked for more details.

We excitedly brought up the idea of getting an MRI to our fertility doctor. She was less enthused than Dr. Reid. She tried to talk us out of it. We never did get to the bottom of why. Maybe she just felt it was another dead end and knew we had suffered enough. For whatever reason, we had to insist that they order it. Finally, she relented.

The MRI revealed nothing other than the presence of a large, previously undetected fibroid in the wall of my wife’s uterus. Fibroid is the term used to describe a non-cancerous growth on the uterus. I think the medical establishment invented a term that was less known than tumor so as not to scare people. But a large tumor is essentially what the MRI found. The clinical notes said “a 6 centimeter in diameter submucosal fibroid needs to be removed” because that sounds better than “you have a tumor the size of a small peach located at a common implantation spot that we totally missed for 6 years.”

Our fertility doctor took one look at the scans and determined it needed to be removed right away. Dr. Reid agreed, since of course we had to double check with him. We found a great surgeon in New York (from a list Dr. Reid created) that happened to be in-network, and off we went for a laparoscopic myomectomy. The software robot had helped us identify the tumor, and now a physical robot was going to help a specialist get it out. What a time to be alive. Until, ya know, the swarms come for us all.

Almost immediately after that tumor was removed, my wife got pregnant naturally. So many people we talk to say this was a miracle. It was, just not in the way they think. The miracle is that by messing around on our smartphones with technology unimaginable just a year before we started using it, we identified and solved the biggest problem we’d ever faced in our life.

A lot of the discourse around AI has become toxic. I was at a party recently where someone started using AI to generate trivia questions. A participant made a joke about how the AI user was condemning a person in West Virginia to drink dirty water by using ChatGPT. This got laughs and approval.

I see midterm election ads in Wisconsin all the time that have scary horror music and make data centers out to be demon factories built by Satan.

I am in the same boat. Me and my coworkers at our small tech company, all avid Claude users, will make anti-AI statements all the time. It seems many of us are in this strange place where we can’t help but use AI but we have to self-flagellate when doing so.

I think there is a whole lot to be worried about with AI development, and I think we should do much more to make it safe. I also think it shouldn’t be lost how it’s helping out regular people in ways that are far more profound than generating trivia questions for drunk people. There is a real chance that I wouldn’t have my son if it were not for AI. Who knows how many other happy babies are being ushered into the world by the weirdest midwife of all time. Can we somehow stop everything right here, where we get magical kid-producing tech for $20/month without the nanobots, hacking, and totalitarianism? A guy can dream.

When naming our child, we did the usual thing where you create a giant list of names and then whittle them down while trying to find something unique and fun that isn’t too strange or too common. Following that comes the process of discarding all the names you find distasteful for reasons such as “the most annoying kid in my 8th grade history class had that name, I’d never use it in a million years.” Finally we settled on one we both loved. We didn’t realize until long after his birth that there might have been a certain TV doctor with a flair for the dramatic who worked his way into our hearts: our kid’s name is Reed.
