Looks like people are really offended by this. Agile lately has been looked at this silver bullet for software engineering. I have worked both in Cisco and some good startups and in my humble opinion having fast paced development and high feature churn rate really is unsuitable for a bank and other infrastructure companies.
Also by hipster, I mean that the banks don't have luxury to experiment with latest trends and the cool tools. They have to stick with the old proven methods.
