Just read that a single 787 Dreamliner has over 2.3 million lines of software code

I was flipping through an old Aviation Week magazine at the break room and saw that fact. It blew my mind. That's more code than some fighter jets from twenty years ago. On one side, it shows how much we rely on complex systems now. On the other, it makes me wonder if all that complexity is a bigger headache for maintenance down the line. What do you all think, is the software load on new airframes getting out of hand?
