I started researching the subject of self-replication in neural networks, and unexpectedly I saw that there is not much research on this subject. I should mention I am new in the field of NNs.
This idea seems to be very appealing, but now I am having problems coming up with an actual use case. The paper Neural Network Quine from 2018 seems to be one of the main ones addressing this topic.
So, what are the use-cases of self-replicating neural networks? Why isn't this subject more thoroughly researched?
