I encounter people and teams that are just unwilling to adopt contemporary development and deployment practices. The article notes that Hipchat was a struggle to get approval for, yet I often run into people at CMS that never log in to it and prefer tons of emails. Deployments aren't automated and still happen for some teams on calls during maintenance periods once a week. I've had people in technical capacities ask what GitHub is.
The problem is institutional, it really has nothing to do with young people working 10 hour days. I care about my work-life balance -- I'm too old to crash on the couch at my startup's office like I did at past jobs in my 20s -- but I also keep up with contemporary development practices, make a point to study a new language every year, read academic papers, and care about my work. I don't think I can say the same about most devs I've encountered in government. The consulting firms are incentivized to build walls and protect the way they do business in order to keep getting that contract money.
If you're an older dev that is intellectually curious in the practice and art of software development I think you'll be fine.
