I think "looks excellent for children" is a sign that it might be excellent for experts. We want something that can represent a system in the clearest simplest way possible. So simple a child could see how it works and so simple that mistakes are obvious. The question becomes "Will Eve scale to systems that solve real-world problems and not just toy examples for kids?" Will an Eve solution for a real-world problem look simpler and easier to understand than it does now in the languages we're using today? One data point in its favor is how much they've accomplished in so few lines of code if the IDE, the compiler, and a relational database are implemented in 6500 lines of code.
