#12See also: https://arxiv.org/abs/2406.19108 > We show that when random, non self-replicating programs are placed in an environment lacking any explicit fitness landscape, self-replicators tend to arise. We demonstrate how this occurs due to random interactions and self-modification, and can happen with and without background random mutations. We also show how increasingly complex dynamics continue to emerge following…

This is every cool research. Do you have any idea why the authors chose Z80 as the program language? I have seen other studies in the same spirit that use simpler toy languages like Brainfuck ( https://arxiv.org/abs/2406.19108 ) and I wonder if you could get higher execution speed if you didn't have to execute so much emulator code. The programs/genomes are extremely tiny. I would be very interested to see what kind…
In that previous paper you cite (by the same group) they tested several substrates for spontaneous replication (BFF, Forth, SUBLEQ, and emulated real CPUs. Z80 and 8080 CPU exps confirmed the rise of self-replicators, with the Z80 notably exhibiting multiple waves of increasingly capable self-replicators.
And the instruction set seems quite appropriate for the experiment: Z80 has native block-copying instructions, while it doesn't have MUL, so the task of evaluating polynomials is somewhat more challenging

#16Tierra[0], written by Tom Ray[1], immediately comes to mind. I was captivated when I read about it, as a teenager, in Steven Levy's "Artificial Life"[2]. Having played Core War[3], the description of Tierra in Levy's book inspired me to play around with making a virtual machine in Turbo Pascal and trying my hand at making a pale and naive clone. It was a lot of fun, and arguably has influenced a lot of my thinking ab…

#17Interesting. But, evolution is way too unconstrained to provide us a path to "agi". It would require too much compute. Evolution also eventually gets frustrated and creates the brain, capable of in context learning. Maybe we should take some notes from these massively parallel, shallow, and highly recurrent constructions.
If evolution had access to TSMC's process technology, do you think it wouldn't leverage it? The signals in my AMD CPU propagate ~1,000,000x faster than the ones in my brain.

#19authors here - happy to answer any questions! we’re excited for this line of work and see this as the first step on a longer journey.

Constrained evolutionary algorithms may have some promise.
