That's a nice myth, however in practice what happens is exactly the opposite, mostly because people lose sight of the whole picture and end up super specialized on small pieces of the puzzle. This is what happens in corporations, where the whole reason for why projects succeed is because of the invested resources, work still being done on the model of the Egyptian pyramids, with thousands pushing large bricks. There's a reason for why micro-services that don't start as a monolith are failing - people have this impression that micro-services are imposing clearer boundaries, which is of course wrong.
