The gap between agent demos and agent products

Every impressive agent demo skips the same three things:

1. Auth. The demo target is open. The real one has a login and a 2FA prompt.
2. Identity. The demo agent acts as the developer. The real one needs its own email, accounts, and a place to keep secrets.
3. State. The demo is one clean run. The real one has to remember what it did last time and resume.

These are not AI problems, which is exactly why they get skipped in AI demos. But they are most of the work to go from "cool clip" to "thing that runs unattended." The model is increasingly the easy part. The unglamorous identity-and-state layer around it is where products actually live or die.

Curious whether people think this layer gets commoditized into the foundation models, or stays a separate thing you assemble.
