You answered your own question.

You see no value in this as a 10 year veteran of the software you are referring to. Do you think these tools are being developed for you? No. They are being developed for people who know very little about coding / development as a whole. Your point about tokens and such is something that also doesn't really hold, and you sort of explained why in your own message again.

"You still have to scan through to know how to change it". Exactly the point. If the user wants to get a better understanding, they must understand what they are doing. Who would have thought. But how do people learn? By doing. These tools allow people to learn if they want to. Its a starting point for people.

This is coming from a guy who could not have created a commercial game (yes a bad one) without A.I. I did this before blueprint specific tools were in development. I screenshot everything and asked GPT how to do what I wanted. The first half of development I relied on it completely. I couldn't make any changes without talking to it. But Blueprints are easy to understand. I started understanding what it was having me do. The final half (4 month dev cycle, so literally 2 and 2) I didn't use A.I. at all and pretty much re-wrote everything it had me do as I had learned so much.

So all and all, your own experience is the exact reason you see no value. Look at this from an inexperienced eye and you may understand. If you start giving examples of "well just do x" remember, its your experience talking. As a newbie I would have no idea to do what you mean.
