I've thought about this issue so very many times, and I feel that until someone creates a system capable of understanding the underlying purpose of the code, we will not be able to automate this stuff away. I think the issue is that all of the things the author wants a breakthrough for is exactly what makes programming hard. We don't have systems intelligent enough to reason about a contract between two systems so as to create a general-purpose solution for things like glue code. The subtle differences that are there and that require us to do this work over and over again with small variations are precisely why programming requires intelligence.
