I think it just speaks to how quickly the tech has developed. Airliners work more or less the same as they did 50 years ago, computers are vastly different (and vastly more powerful).
Airliners may look the same but they don't work as they did 50 years ago when the was no fly by wire in these planes, no high-bypass engines, etc.
