How Programming Will Look In the Future?
Programming has largely stuck to the von Neumann paradigm since the 1940s, but modern hardware with multiple cores faces challenges with this model. Traditional concurrent programming solutions like Go's goroutines introduce complexities. Data flow programming offers an alternative by treating programs as networks of independent nodes that pass data, avoiding race conditions and allowing natural parallelism. Nevalang is a new language built around this paradigm, offering a promising future for programming. However, it is still in development and looking for contributors.
