Global workspace theory,4 or GWT, describes the human brain as a collection of specialized modules sharing data through a central, limited capacity bottleneck. Most machine learning architectures already satisfy the first three indicators5 of this theory. However, they consistently fail to implement GWT-4, the requirement for temporal persistence. To address this, we use the framework of computational self-availability, or CSA. This describes a system where internal processing is available as an input to the system itself.

Reviewing AI generated code can be tough, especially if the code generated is solving a particularly complex problem. Even if the code is correct, it can be hard to understand how exactly it works. When working with other human programmers, I would generally ask them to walk me through their code, and I would ask questions about why they made certain decisions as we go. I wanted a similar process for reviewing AI generated code. After a lot of exploring, I've found a combination that works well for me.
