Curiously the claim sounds like learning this programming language is equivalent to reading the whole DDIA book. :P

Much like C abstracts over machine code or Python over C, Acton attempts to provide abstractions that let you treat multiple computers connected together in a distributed system, as a single logical machine, much like programming your own local computer. This is what the "made easy" alludes to.

Acton leans heavily on actors and actors are already like small little processes that do their thing. With a distributed run time system, we can spread actors across multiple computers, yet let them communicate to each other, much as if they were on the same computer.

Elixir is pretty easy
