I give self-replicating factories a higher probability than AGI. We'll probably have a 100% automated stack that can replicate and repair itself, as well as produce everything we need, all based on locally sourced and plentiful materials, before we have human level AI. It will be a manufacturing singularity. We should bootstrap automation in itself, like we bootstrap compilers. Object production would become similar to compilation, from source code to material object. We'd have optimized material compilers.
When we have a replicator, anyone can have one. Industry would become like agriculture, if you have the initial seeds, you can plant and then you bootstrap your crop.
If you think about self replication, on the whole, industry is a self replicator right now. But we need to make it fully automated, reduce its minimal footprint and make it less reliant on rare materials. There is a need for sustainable, smart materials and open source automation and AI in order to save the population from disenfranchisement. Capital and the means of production should belong to all of us, not just the 1%.
