Fascinating roundup of voice and bot-based UI's. Great simplification of the situations where it's valuable and where things will evolve vs. the situations where it's merely novel and trendy. Most interesting insight was that it's driven mostly by developers being able to adapt and update these UIs quickly with little to no front-end implications – and developers being familiar with the command line, and trying to push that interface into the public, by systemizing user response syntaxes.
