I don’t think you can make a kite that can last a decade of load. We just don’t have materials strong enough. Also you need a sophisticated algorithm to fly it and never crash
Modern kites are made of nylon and kevlar. With regular maintenance these kites should last at least a decade. Cables might have to be replaced every few years.
As for the flying algorithm, I doubt it has to be very sophisticated at all, especially if the kite is itself designed to self right and stabilise. After all, a single line kite has 0 controls.
