In the late 1970s and early 1980s, domain-specific programming languages sprung up. Languages for simulating economic systems, for a company's financials, for modeling biological systems, and many more. Now, in the twenty-teens, functional programming is gaining new traction as developers learn that, at their core, they start with defining a domain-specific language. The tools for creating domain-specific models are orders-of-magnitude too abstruse, complex, arcane, and difficult. If Eve can make creating and playing with models even one-order-of-magnitude more accessible, it will help shift much of programming up a layer of abstraction.
