# Digital Infrastructure
**Entity class:** Technical and civilizational infrastructure concept
**Domain:** Artificial intelligence / governance / public knowledge
**Maturity:** Developed
## Definition
Digital infrastructure is the software, networks, data systems and computational control layer upon which growing portions of physical infrastructure depend. AI reliability becomes a material-world concern when atoms are governed through code.

## Simple Reminders, Quotations, and Thoughts
> “Though these models mimic human writing and are trained to mimic human emotion, these are not human minds. They don't have bodies or parents. They did not get bullied in elementary school or mentored by a kind uncle when they were young. They are brilliant where we struggle and childish where we excel. A chimp cannot read as we can, but it can climb trees as we cannot. These are digitally native intelligences navigating digital worlds, and our world is increasingly built atop the digital world. Our physical infrastructure is a layer of atoms atop code. That the AIs act reliably inside the digital world upon which ours depends is critical to our future, and right now the AIs are not acting reliably.”
