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?

Honestly, the part that gets me is the supply chain for that code. It's not one team writing it all. You've got dozens of contractors and subcontractors, all using different tools and standards. Keeping all those software packages talking to each other, and updated, over a plane's 30 year life sounds like a nightmare. The real risk might not be the code itself, but how it all gets stitched together from so many different places.

Yeah, that's the real scary part nobody talks about. The patchwork of old and new code from different companies has to be a mess to manage. Makes you wonder how anything stays working at all.

Totally. It's like that with so much stuff now (phones, cars, even smart home gadgets). Everything's just layers of old and new stuff from different people, held together with digital duct tape.
