I take that paper quite seriously.

Don't get me wrong. I don't have a deep enough understanding to judge the paper. I just love arxiv because it is a sounding board for ideas that otherwise would have a much smaller audience. Only on arxiv can you find conclusions like that.

I read this through once, and I need to again. There are certain parts that I am attracted to:

The output of the Maxwellian Robot is collection of points (subset) in some space. They self-replicate or self-print the space. Their motion is the generation of the space, or the printing of the space.

This is something sensible to me. I've been long thinking on the inextricable link between matter and space, and I like the fact that this brings irreversibility into the relationship. But, I am only beginning to absorb this. Some immediate questions: What defines the collection of Maxwellian Robots, and what is being filtered? Does this describe the nature of physicality, or is it a useful analogy? To the descriptive end, the causality seems the most compelling part, but can something fall out of it that maps onto the physical laws?

I'd love to have a beer over this. I need someone to sit down and walk me through it.

I don't think the nebulae/Shrodinger’s equation solutions is strongly supportive. It feels like cherry-picking.
