Could you build this?
Partial Setting up an LLM agent that edits files is simple, but orchestrating isolated self-modifying virtual machines with automated snapshotting and hypervisor orchestration requires custom cloud/virtualization plumbing.
What it would actually take: Built with Python/Go orchestrating MicroVMs (such as Firecracker or Cloud Hypervisor) or cloud VM APIs. The difficult components involve safe self-modification loops (sandboxed config verification, automated rollback on boot failure) and secure VM lifecycle management with low-latency host-to-guest RPCs.
Discussion
16 comments analyzed.
Competitors mentioned: OpenClaw, Graphiti, Qdrant
Concerns raised: Lack of verification/explainability at scale for autonomous decisions, Security risk if agent installs compromised packages or exploits, Unclear cost/API burn rate and billing controls, Liability and governance when autonomous agent causes damage, Self-modifying config can be liability if wrong
Feature requests: Cost monitoring/spending controls to prevent runaway API usage, Built-in verification layer for autonomous outputs, Better documentation/visibility into what system builds and why

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
