"Deep research" is super impressive, but so far is more "search the web and surf pages autonomously to aggregate relevant data"

It is in many ways a workaround to Google's SEO poisoning.

Doing very deep research requires a lot of context, cross-checking data, resourcefulness in sourcing and taste. Much of that context is industry specific and intuition plays a role in selecting different avenues to pursue and prioritisation. The error rates will go down but for the most difficult research it will be one tool among many rather than a replacement for the stack.
