It feels like this to me too, whenever I give it a try. It's like a button you can push to spend 20 minutes and have a 50/50 chance of either solving the problem with effortless magic, or painfully wasting your time and learning nothing. But it feels like we all need to try and use it anyway just in case we're going to be obsolete without it somehow.
If it doesn't work, it's an annoyance and you have to argue with it.
If it does work, it's one more case where maybe with the right MCP plumbing and/or a slightly better model you might not be needed as part of this process.
Feels a bit lose-lose.
