Luxury car has more than 100M lines of code, while F-22 Raptor has only 1.7M lines of code. Mercedes-Benz S-class only the navigation system contains more than 20M lines of code.
From somewhere else I found that average car from Ford contains more than 10M lines of code. I think we are doomed with this trend. Everybody seems like to reinvent the wheel again and again, no matter how lame they are with it.
Same thing happening in the web world, every several months, there are some new kids on the block trying to solve an old problem with a completely new approach. “You don’t throw away the baby with the bath water”, there is some quote like from from Drizzle project (the re-vamp of MySQL project), if I remember correctly. So many NoSQL products are trying to replace the existing rock solid MySQL, backed by remarkable marketing hype (and propaganda campaign machines). Only time will tell, just like how MySQL survived so many years.
[update] A colleague found this link, amazing: F22 got zapped by International Date Line.
