If software engineering is shifting, it's shifting due to the youth of the discipline. Remember, we've been building bridges for thousands of years. We've had a lot of time to figure out how best to do it. The amount of improvement we've had in 50 years in terms of technique is probably pretty small; improvement in materials is the more likely reason for any variations in technique.
