LiveView is the brainchild of Chris McCord. He did the prototype on Rails before getting enamoured by Elixir and building Phoenix to popularize the paradigm.

LiveView is amazing and so is Phoenix but Rails has better support for building mobile apps using Hotwire Native.

Not everyone can make a dramatic switch of languages and frameworks. Turbo is excellent at what it does. Pure joy to use, replacing much of our Vue frontend.
