I feel consoled in the fact that airplanes use less code than modern luxury cars, especially German ones, given their reliability record.
It also makes sense for avionics software, especially in fighter jets, to contain as few lines of code as possible, increasing the efficiency of the software while reducing possible points of failure. On the flip side, it means the cost for engineering the Raptor's 1.7 million lines of code costs far more (on a per-line basis) than the Dreamliner's 6.8M or the S550's 100M lines of code.
