That's on company making the agentic harness. Hiding details of what computer does from the user is the original sin of this industry, and subsequent generations of developers and software companies keeps doubling down on it.

(Case in point - I just downloaded the Codex app for Windows, and in the options I see it has two UI modes of operating, one of which is meant for "non coding" and apparently this means hiding the details of what the agent is doing. This is precisely where the layman is betrayed by the tool.)
