Robustness/resilience/durability were high on the design criteria, not a desire to pioneer for pioneering sake. As the article is in an IBO newsletter article I don't feel it right for me to publish it. Doubtless your local friendly Organ Builder has a copy and can share. As a former computer hardware/software designer/engineer I have to say that I can't see anything in what has been done that would cause any real concern - unless you believe that the sort of logic/circuitry that permeates your car, your heating system, your oven, your 40 yr old calculator etc etc is so full of new fangled gizmos that it must be inherently unreliable. (I should also point out that my day job involves an organ with a key and stop action that was 'breadboarded' 44 years ago which is still going strong today).
