“Cure” is a tough bar, but I believe Paxlovid, the anti-viral used to reduce Covid severity, was identified using ML. There’s many companies like Recursion Pharma which are entirely focused on using ML for drug discovery, and from what I can tell seem to have promising results, but drug development is slow enough that nothing will come of it for a while.

Also, while not medicine focused, Google’s GNOME project results announced a few weeks ago was pretty remarkable. They discovered more theoretical new materials using their ML approach than the rest of human history combined, and they are already confirming many of the results in laboratory settings. That has the potential to be a revolution in limitless scientific and engineering applications.
