The pattern-matching, actors, and pipeline operator seem like they were inspired by Elixir. Was that a conscious source of ideas or just stuff you came across elsewhere and thought was good?
I'm not too clear on the details since I don't know the language, but I think that Rust's (http://www.rust-lang.org/) concept of "ownership" does something very similar to what you're suggesting.
I started learning Elixir a few months ago, and the few times I've had to dive into reading some Erlang source code to figure out an issue with a library I was using I've been surprised at how easy I find it to read. Even though the syntax is quite foreign, having learned the general ideas of pattern matching, etc. in Elixir makes it a lot easier to read Erlang code.
I don't think I'd ever set out to write a new project in Erlang: for me Elixir has all the advantages and none of the drawbacks. There's nothing you can do in Erlang that you can't do in Elixir, and you get the benefit of a much more expressive syntax and powerful metaprogramming. But there are a lot of quite mature Erlang libraries out there, and I don't see the point of replicating them all in Elixir, so I can see myself contributing patches to Erlang projects.
Have a play with both, stick with whichever one feels better to you. Since you're just learning, you want whichever one will make you more excited about learning, and make it quicker to pick up the concepts. Once you've got a solid grasp of it, you can familiarize yourself with the few syntactic differences and make a more informed decision about which one you want to keep working with.
The author seems to contradict himself in the conclusion: while earlier he states that the Android share icon is also used by ShareThis, and that variations on it comprise the majority of search results for the term "share icon", he then concludes by saying that the Apple/iOS icon is "suitable to use in a general site/app", while the Android icon is "suitable to use in an Android app".
I think the author's own greater familiarity with one icon (by virtue of being an OSX/iOS user) has led him to make an overreaching conclusion about the wider population.
