I do like the move that the industry is making toward local intelligence. It helps a lot in troubleshooting issues and keeps a lot of the spaghetti wiring to a minimum. In addition, it allows status feedback to the operators so that they can tell immediately what the problem is rather than having the maintenance engineer hook up a bunch of diagnostic equipment.
Not only is localized intelligence making life easier for problem solving and debugging, but the costs are becoming lower and lower which only helps drive the localized solution. Becoming more affordable will allow more solutions, and better designs, to occur with a minimal amount of fuss by engineers.
