I think there are lessons to be learned.
Here's how it started for this guy:
starting with the realization that my God of the Gaps was gone.
A lot of not dumb people have trouble with
“How could all of these amazing forms of life, myself included, have just happened to arise?”
I watched the following BBC Documentary a while back. Some interesting stuff I hadn't seen before, and I've done the whole machine learning schtick, where it's obvious recursive iterative processes with cost feedback can do most anything.

The title seems a misnomer, as it was more about systems producing spontaneous order than chaos.
Add to these physical examples of spontaneous order a little background in computational learning and optimization, and it's completely obvious that with billions of years and bazillions of stars, the universe can churn out things with tremendous function.
(Me, I find it strange that people make such a big deal out of evolution, while embryonic development and morphogenesis is about a zillion times more amazing, as it turns one tiny little undifferentiated blob into a baby in 9 months. )
I think the other hangup about evolution is conceptual. High school biology talks about species - at least back in my day. Then a creature is of one species and not another, so how could it magically transform form one to another?
If you take a nominalist approach instead, and just note the diversity of creatures, with varying degrees of the ability to interbreed, it's no shock that the population statistics change over time, and interbreeding clusters merge and split and move in state space.
Physical spontaneous order plus some simulations of spontaneous order, functional development, and population evolution and clustering. It's simple, when the right pieces are presented. Most people haven't seen those pieces.
This person seems to have the virtue of non-compartmentalization. What rationalist skill can we learn from this? Maybe look for ways a strong belief in one domain, to another where it's more testable?
