I can't believe this discussion

. Existing engine technology is so old even a lawnmower would be embarrassed

Lets see instead of the typical turbocharged flat engine dance of throttle, prop, mixture, cowl flap, airspeed, while obsessing about EGT, CHT, and fuel flow; you get one lever and " pilot management "
means push to go and pull to whoa. Oh yeah and to start it turn the key, just like a flat engine except when it is cold, hot or somewhere inbetween.

I have over 4000 hours behind or beside GA piston engines from the C65 to the GTSIO 520 and I for one think the advantage of FADEC type technology is long overdue. Oh and by the way I once had a total engine failure ( in a single ) due to a failure of the oil pump, yet I have never landed in a aircraft that was electrically dead, so BRING ON the FADEC
