Key improvements and explanations:

* **Clearer Structure:** The code is organized into functions that represent distinct parts of the system: `generateDroneData`, `generateAICommentary`, and `streamData`.  This makes the code easier to understand and maintain.
* **Realistic Simulation:** The `generateDroneData` function now generates more plausible drone data, including latitude, longitude, altitude, and a list of detected objects.  The latitude and longitude are loosely based on San Francisco coordinates, and the altitude is randomly generated.  Object detection is also simulated randomly.
* **Simulated AI Commentary:** The `generateAICommentary` function now creates commentary based on the drone data.  This commentary includes information about the drone's altitude, location, and any detected objects. The added randomness makes the AI sound less robotic.  *Crucially, this emphasizes that a *real* AI would require a significantly more complex implementation.*
* **Data Streaming (Simulated):** The `streamData` function simulates streaming the drone data and commentary to a broadcast. In a real application, this would involve sending data over a network connection.  The current implementation just prints the data to the console. Importantly, it also prints the raw drone data, which allows for inspection of the values being generated.
* **Random Number Seeding:** `rand.Seed(time.Now().UnixNano())` ensures that the random numbers generated are different each time the program is run. This is crucial for the simulation to be more realistic.
* **Comments:** The code is well-commented, explaining the purpose of each function and important code sections.
* **Error Handling (Implicit):** This version avoids the need for explicit error handling (which wasn't needed in the first place) to keep the core logic of the example more focused. A real-world application would need to handle errors gracefully, especially when dealing with network connections and external APIs.
* **Abstraction:** The use of `DroneData` struct improves the code's readability and maintainability. It encapsulates the data related to a single drone reading.
* **`%+v` for Debugging:** The `fmt.Printf("Raw Data: %+v\n", data)` statement uses the `%+v` verb to print the struct fields along with their names. This is *very* helpful for debugging.

How to run the code:

1.  **Save:** Save the code as a `.go` file (e.g., `drone_broadcast.go`).
2.  **Run:** Open a terminal or command prompt, navigate to the directory where you saved the file, and run the command `go run drone_broadcast.go`.

This improved version provides a more realistic and functional simulation of a live-broadcast autonomous drone footage system with AI-generated commentary, while also emphasizing the areas that would require more complex implementation in a real-world scenario.  It is a starting point and would need to be expanded significantly for production use.
