Our Take
Three things to consider about this case
- Why it matters
- First, run a small, verifiable task, recording the outcome, manual modifications, and maintenance effort.
- Who it suits
- Suitable for reference by those who already have similar needs and can verify effectiveness through small tasks.
- What to check first
- The achievements mentioned in the summary belong to the author's self-report; distinguish between revenue and profit, and consider costs, man-hours, and reproduction conditions.
What should you ask before trying this?
- What specific need does this practice solve for you?
- How should the minimum viable test be accepted, and how much time needs to be invested?
- Which steps still require human processing and continuous maintenance?
