Tourist, I suppose I should expand on my imaginings (although I feel I need to tread carefully around this topic). If either system was to be hacked then you're right, the result could be mission failure for either platform - so no difference in loss. However, the F-22 has the advantage of a human who could save the machine / prevent nefarious weapon employment. Although the human would be a greater loss if the system was to be lost... It was just my mind rambling...
