This is a good way to evaluate the technology.

Acne is a real problem for some people, but comparatively low stakes, mostly visual evaluation, and with pretty well-known solutions. (Of course everything has corner cases, but in general this is a well understood area.)

I have no idea how well this will go, but starting here rather than, say, robotic cancer treatments, can help AI medicine develop into more.

If it does go badly, then after a year we can re-evaluate and either give up or refine the system.
