In practice, today we can solve any control logic problem with existing programming techniques as long as we can specify all the inputs, states/transitions, and outputs. There are techniques to formally verify these programs so you can trust them for mission critical systems - they do exactly what they're designed to do, nothing more, nothing less.
I don't see this approach changing anytime soon. An AI designing a complex system is for the foreseeable future, science fiction. However what's interesting about The Human Brain Project is that it doesn't make any claims about AI, which is actually a good thing. If they start emphasizing AI research I seriously doubt they'd get very far. From what we understand about neural networks and machine learning, which incidentally have very little to do with AI, often turn out to be very good at solving very hard to describe problems like image recognition.
I think if The Human Brain Project focuses on better understanding our neurons and how they work, and are able to translate it to advanced neural networks - these systems could turn out to be adept at solving certain problems. That's a good thing.
