Is Deep Research amazing or worthless?

We've spent the last week stress-testing the new "Deep Research" capabilities from OpenAI and Google. The consensus? It's great at processing language, but lacks the motivation, instinct, and persistence required for genuine intelligence work.

When a human analyst hits a dead end, they make a phone call. They check a different registry. They posit a new hypothesis. When an LLM agent hits a dead end (e.g. "page not found"), it hallucinates or gives up.

Use it for summarization. Use it for translation. But do not mistake it for investigation.
