No, productivity has increased massively, but not due to better editors or IDEs. Those have shown only marginal improvements, if any. (Is any modern environment more productive than a Lisp Machine or Smalltalk?)

But some of the main productivity drivers are distributed version control systems, dependency management libraries, and sites like GitHub for sharing code and libraries.

Being able to automatically generate a project from a template, and pull in any open source library written by anyone on the planet with a single line in a config file, is amazing.

Also, remote hosting and cloud provisioning to quickly deploy any code to be used by anyone in the world with a web browser. Arguably even app stores by eliminating the need to figure out distribution and payments on your own. (The stuff maybe not everyone considers "development", but is key to the overall productivity of any software project.)
