Conventional wisdom regarding finishing cutting boards and other food prep surfaces is to coat them heavily with mineral oil and/or a food safe paste wax to "seal" and/or "condition" them. Seri Robinson asserts otherwise, her research has shown that any finish applied to wood decreases its natural anti-microbial properties.

Dehydrate and die is more accurate

We live in a sea of dead and alive microbes, it's fine. Cooking food kills them and we consume them with every meal

I'm not so much concerned as interested, in this person's proposed model, what happens to this accumulated detritus. Maybe it's just that it's negligible. But it must accumulate

The illustrations seem to indicate that stains and dead microbes accumulate in the middle of the wood, deep below the surface. It would be interesting to slice an old wood cutting board in half and see the accumulated stains!

That penetration is super exaggerated. Ever cut through a stained (i.e. pigment-stained) board? Board painted with a water-based paint? Those paint pigment particles are same scale as microbes, so you should expect them to penetrate to similar depth. Surface cleaning and routine abrasion get rid of most of it. Go over the surface with a scraper - take off 20-50 microns - and you're pretty much down to virgin wood.

You're on to.something here. And you're right: that illustration probably distorted my understanding of the process

Maybe, but your examples aren’t repeatedly wetted and dried. Could the repeated cycles cause the particles to move deeper?

Nobody says You can't wash the thing occasionally
