> Right. But even with a DBA, the possibility remains. We accept that.

You're forgetting the element of scale and replication. How easy it is to bribe a DBA of a major platfoms like Gmail? How easy to replicate the same destructive behavior to other DBA? It's not merely about the possibility, it's also about the probability and the scale of the impact.

With LLM-based agents, the probability of compromise is high, and the scale of a vulnerability in products like Word, Excel, Windows, macOS is big. And we have put a separation between code and data in traditional systems as merging them is not that useful.

> Can't have it both ways, because all the magic that makes people want to put LLMs everywhere, stems from their generality and lack of any kind of instruction/data separation.

The issue is not the LLM. The issue is the harness those products wraps the LLM in and insist on making tools act according to the LLM's output. Having unreliable (as in uncontrollable) output be the control plane of tools is the issue here. Both the LLM input (prompt+user data) and the output should've stayed in the data plane and not move in the control plane.
