Self-replicator that is simultaneously created and destroyed may lead to better

"Similar to how living organisms grow and regenerate new cells, the amphiphilic product is an autocatalyst that has the ability to self-assemble, thereby increasing its concentration or "growing." As the product both self-assembles and continues to be generated from the raw materials until they run out, the product concentration grows exponentially, at least for a while. But—like life—this product is thermodynamically unstable, so that at the same time that the product is being created, it is also decomposing into a thermodynamically stable waste product."
