Subsingularity/Modosophont (S0) Technologies

The complete toolkit of a baseline, un-augmented human civilization, operating entirely within the limits of classical physics and pre-singularity understanding. This is everything we have now or can plausibly achieve without self-improving AI or intelligence amplification: fossil fuels, fission power, chemical rockets, classical computing, biotechnology as we know it, and materials science based on atomic-scale manipulation. It's the technology of a species that is still the master of its tools, not the other way around. Powerful, but bounded by human cognitive speed and biological lifespans.

Subsingularity/Modosophont (S0) Technologies *Example: Everything from a steam engine to the Large Hadron Collider, the Hubble Space Telescope, a CRISPR gene-editing kit, and the International Space Station are S0 Technologies. They are the pinnacle of what a civilization can build when its smartest minds are unaugmented humans working over decades, using tools that don't fundamentally redesign their own inventors.*
