- Praise: Using Sandvault for sandboxing AI agents introduces a novel approach by leveraging Unix user systems, enhancing security through unprivileged user accounts.
- Praise: QubesOS offers kernel isolation via a hypervisor, which could provide a robust solution for sandboxing AI agents if usability improves.
- Concern: WebAssembly's current limitations in language support hinder its viability for sandboxing arbitrary code, which poses challenges for developers.
- Concern: The complexity of using QubesOS as a daily driver may deter users from adopting it, despite its potential benefits for sandboxing.
