The '🤖machines will replace doctors👩🏽‍⚕️' debate turns 70! From Warner Slack to Geoffrey Hinton. (Part 1 of 6)

What do the invention of television and fuzzy logic have to do with AI in medicine? More than you'd think.

Welcome to AI Health Uncut, a brutally honest newsletter on AI, innovation, and the state of the healthcare market. If you’d like to sign up to receive issues over email, you can do so here.

Fun fact: The same person who invented television also played a significant role in the early development of AI in medicine.

Another fun fact: PROMIS, the first medical record system I discuss in this article, was already using a touch-screen terminal back in 1967!

History isn’t just fascinating. It’s full of crossovers that make Marvel jealous. 😊

In this 4-part series, I thoroughly review the 70-year history and research on the ‘machines replacing doctors’ debate.

But first, some housekeeping:

• First, apologies to my paid subscribers and Founding Members who’ve been patiently waiting for Part 2 of my series, “These 14 Health AI Companies Have Been Lying About What Their AI Can Do.” It’s coming, and trust me, it’s going to be a bombshell. In the meantime, here’s a little (and super obvious 😊) pre-release quiz: Which so-called health AI startup just raised $165 million, is valued at $0.5 billion, and is riding on stolen tech? Stay tuned for Part 2...

I’m looking for people who are worried about the future of healthcare but hesitant to speak up, whether out of fear of retaliation from their boss or other concerns. I’m particularly interested in compelling inside stories from digital health and health AI. I believe that combining “mosaic theory” analysis with firsthand accounts from within companies is the key to revealing both the positives and the negatives in our industry. This approach is how my recent pieces on Walmart Health and IBM Watson Health came together—thanks to individuals who stepped forward to share their stories. Friends and colleagues who’ve known me for years can vouch for my discretion and integrity. I will always honor anonymity, and I will never act without a person’s consent.

Now, for the big announcement:

🚨 Attention, my paid subscribers and Founding Members: In 2025, I’ll be launching a new series of articles, tentatively titled “Venture Capital is a Scam: Building a Better Way to Fund Innovation,” with a sharp focus on the digital health sector. I want to expose the net harm that venture capital has inflicted on digital health innovation over the past 20 years. Innovation in digital health is at an all-time low, and it breaks my heart. This is an urgent matter. The goal of this research is to explore alternative methods of financing and capital allocation in digital health and healthcare AI. VCs are optimizing their picks and managing startups in their self-interest—not necessarily in the interest of founders, and certainly not in the interests of customers, patients, and clinicians.

With this in mind:

1. I welcome any ideas, research, and inside stories from within the VC world. A significant portion of what I write is heavily based on these insights. I understand that trust and loyalty are everything, and I will never disclose anything without your consent.

2. The amount of information and data I’ve collected so far could fill, if not a whole book, then at least half of one. I know it’s a long shot, but if anyone is interested in financing my research in the form of a book 📚, I believe it could greatly benefit the healthcare industry. This book could help break the healthcare oligopoly, expose the shady schemes of venture capital, and create a better way to build an ecosystem of innovation in healthcare. I’m a one-man operation—no sponsors, no advertisers—and unfortunately, I don’t currently have the means to write a book like this on my own.

Thank you!

All right, let’s get back to our story.

First things first—let’s all take a deep breath and lay out the facts.

The debate over who’s better and when, exactly, the medical profession will fade into the abyss has reared its head once again last week. So I’m here to calmly summarize the latest research on the subject. Yes, there will be some sarcasm sprinkled in, but the goal is simple: gather the research, opinions, and quotes from people much smarter than me (all 184 of them 😊), and let the readers make up their own minds.

Following the lively discussion on X spaces organized by Sanat Dixit, MD, FACS last week—where I had the honor of being a guest speaker—there was a robust exchange of ideas from notable medical professionals such as Anthony DiGiorgio, DO, MHA, Owen Scott Muir, MD, DFAACAP, Anish Koka, MD, Chuck-G, John Paul G. Kolcun, MD, Krishnan Chittur, and many other experts. This led to a fresh debate on whether AI will be “replacing” doctors anytime soon. We covered a lot of ground during that conversation, and the recording is available here.

And now, here are all the honorable mentions in this article—yes, all 299 of them. 😊

Wow, that’s a ridiculously long list—299 unique mentions, to be precise. We’ve got 184 individuals, 79 companies/organizations, and 36 products/systems.

Before we dive in, let me make one thing clear. I’m over this tired line, but I have to mention it for the sake of completeness: “AI won’t replace doctors, but doctors who use AI will replace those who don’t.” It’s been thrown around for at least 5 years now (any guesses on who said it first?). At this point, it’s obvious, and frankly, I’m sick of hearing it.
