Very well. If it's math, them, it;s at least quasi-Platonic and that is well-above my pay grade intellectually. How math principles become cells is an intense topic. It's a pity we cannot yet produce this today. Set up an experiment and evolve basic elements into something that quacks. Noteworthy, if possible?

The main problem to be solved is how to get from building blocks to machines. The problem has actually little to do with biochemistry, it's a mathematical problem because you would always stumble on that problem in any model of artificial chemistry. The solution is percolation in 3 dimensions to get from building blocks to a large number of micro-environments with features in the interior that can act as catalysts. Each micro-environment breaks symmetries in different ways, some are are better than others for harboring an RNA world than others.
