On Saturday, Dario Amodei claimed (in a long defense of his company’s approach to AI) that he thinks it “will actually be possible to cure most human disease in ~5-10 years”, highlighting “curing cancer” among other goals. As usual, some in the media ate it up.

And I wish it were true. But his timeline is so naive as to be absurd, both with respect to how medical science works and why it is challenging.

If you haven’t already done so, I strongly recommend you read (or reread) the March essay I wrote about AI and cancer, which builds on an essay by Emilia Javorsky. That essay started with Javorsky’s observation that (as of March) not one drug designed by AI had yet reached clinical adoption, even after over a decade of efforts.

Part of the crux of my essay (and hers) was that even if AI were a lot better, curing disease is hard, both economically and technically, and you also can’t simply skip the time-consuming clinical work. (I further argued that we don’t really have the right kind of causally- and biologically-sophisticated AI yet. New advances in AI and math don’t fundamentally change what I wrote there.)

The happy news is that you don’t have to take my word for any of this anymore. The mood has changed, and this time a whole pile of people pushed back. I have yet to see Amodei’s ridiculous claim dissected in the mainstream media, but below are some of the many tweets over the weekend that rightly took Amodei to task.

Let’s start with Eric Topol, a well-respected and very pro-AI physician/researcher who is having none of it. (Topol also notes that Hassabis made a similar absurd argument last year on 60 Minutes, maybe the most naive things I have ever heard Hassabis say. AI might someday contribute as Hassabis says, but certainly not in the next decade. Many of the quotes below happened to be directed to Amodei, who was in the news, but apply to what Hassabis claimed as well.)

I'm keen on AI having a transformational impact on human health. But these cure projections are wildly off-base and impossible.

By way of setting realistic expectations, Topol adds:

Sorry, but anyone claiming AI is curing most diseases in 5-10 years is spewing magical thinking & it’s very cruel for patients to be misled this way No matter how clever your AI is, proving we can trust it is clever takes preclinical & clinical work, which eats that timeline

2/2 Second, on the messaging around AI. I do not agree that my messaging has been disproportionately negative. In fact it has been about equally balanced between risks and benefits: I’ve written one major essay about each, and even in interviews where I discuss the risks, I

Cancer biologist John Herrman wrote (plausibly if optimistically, but nowhere near as optimistically as Amodei):

John Herrmann, PhD@ablT315I

@EricTopol @GaryMarcus Much more defensible: AI could plausibly accelerate a few medical breakthroughs over next 10 years that surpass today’s best advances. That’s far different from “AI will cure most human disease” including complex dynamically evolving disease states like many malignancies etc

MD/PhD Marios Georgakis asks:

(As far as I know, the correct answer to the question about real plans posed in the first sentence is a simple “no”.)

The software engineer/enterpreneur Chombe Bupe, responding to Georgakis, adds:

Chomba Bupe@ChombaBupe

The lack of causal understanding in today's artificial intelligence (AI) systems means the models would generate a ton of proposals for potential cures for diseases most of which would be wrong & it would take a lot of effort to wade through all of that slop, I mean proposals.

Marios Georgakis @MariosGeorgakis

Has any of the AI companies ever presented a real plan for how they are going to cure even one disease in 5-10 years? This doesn't just sound crazy to ordinary people, but also to any clinician or drug developer I know. Beyond the fact that we still have very few true cures for

Even the ultimate AI optimist, Wharton professor Ethan Mollick, wasn’t really buying:

Ethan Mollick@emollick

I, also, would like more precision around discussions of how AI will cure diseases. I assume it means "a nation of geniuses in a data center will invent things that should in theory cure diseases" but there is a real big gap between that and actual trials & proof & FDA approval.

Penultimate words to Dr. Catharine Young, a Senior Fellow at the Harvard Chan School of Public Health, in a brutal pair of tweets further underscoring Amodei’s naïveté with respect to medicine.

Dr. Catharine Young@DrCatharineY

PSA: Cancer is not one disease. It is more than 200 distinct diseases, all with different causes, biology and mechanisms. Scientists who study cancer rarely talk about “curing cancer” because it’s nothing more than an empty slogan.

There are a great many things about Amodei that I respect, including both his technical chops and business sense, as well as his bravery in standing up to the US government on important matters. But his habit of giving people unrealistic hope is not one of them. (See also the time he claimed that AI could double human lifespan by the end of the decade.)

In fairness, Amodei may believe what he says, but in that case he ought take Dr. Young’s suggestion of doing a medical internship, in order to better calibrate his understanding of the challenges in medicine.
