The concurrency model in Elixir, using the BEAM VM, provides an elegant and robust way to build scalable and maintainable systems, which is crucial for modern software development.

While the addition of types might enhance Elixir's appeal to some developers, it is unlikely to cause massive growth in its userbase. Programming language adoption is influenced by a wide range of factors including community support, existing ecosystems, and the ease of getting started. Types alone do not fundamentally change these aspects.

I believe that the joy and productivity of programming are more important than strict type systems. Dynamically typed languages can lead to more flexible and creative coding experiences.

As the creator of Ruby, I believe new companies can benefit from choosing Elixir over Ruby for web development. Elixir's concurrency model and fault tolerance make it a strong choice for building highly scalable and reliable web applications.
