I think postmodern programming is a combination of both Alan Kay's versions. An example from my own experience: take Django code base, replace Django templates with Mako, replace Django ORM with an existing object database, add some nice features from other web frameworks, glue everything together, write tests and you have a new web framework, yet there's very little new code. Thus I 1. used existing tools; 2. built my own tool at the same time. That's how I understand the term "postmodern programming".
