1. focus on data processing rather than imperative way of thinking (esp. functional programming)
2. abstraction over parallelism and distributed systems
3. interactive collaboration between developers
4. development accessible to a much broader audience, especially to domain experts, without sacrificing power users
In fact the startup I'm working in aims exactly in this direction. We have created a purely functional visual<->textual language Luna ( http://www.luna-lang.org ).
By visual<->textual I mean that you can always switch between code, graph and vice versa.
What do you think about these assumptions?
