On his blog post you can read some things what is in his oppinion old software, for example he means that the crawler for the google search is 10 years old and completly obsolet. Other technologies are also "creaking dinosaurs" he says

Protocol Buffers, BigTable and MapReduce are ancient, creaking dinosaurs compared to MessagePack, JSON, and Hadoop. And new projects like GWT, Closure and MegaStore are sluggish, overengineered Leviathans compared to fast, elegant tools like jQuery and mongoDB. Designed by engineers in a vacuum, rather than by developers who have need of tools.

In the short time I've been outside Google I've created entire apps in Java in the space of a single workday. (Yes, you can program as quickly in Java as in Ruby or Python, if you understand your tools well.) I've gotten prototypes off the ground, shown it to people, or deployed them with hardly any barriers.

 I completely agree that the most big companies are totally inflexible, and have fear for new technologies and dare not to change the current stable  working technology, but they want that you enhance the old dinosaurs, so that the old software and technology are able to concurrent with completely new powerful software.

Just my 2cents
