For most projects I've worked on in the past 10 years, the energy has majorly shifted towards front-end development. Building blocks have improved dramatically, but expectations have been rising even faster.

Backends are getting more and more homogenized. There's still a fair amount of work that goes into accurately implementing business rules and a much bigger focus on quality and maintainability than ever before. But there's not a ton of serious thinking involved. I can pretty much follow a script for implementing microservices that will scale up to millions of users. I somehow ended up with a high-paying enterprise architect job and when they ask how we can build a system that will have 1000 users, the answer is that you can do pretty much whatever the hell you want so long as the framework is less than 5 years old and it will be fine. Then I go get a coffee.
