I would amplify this by pointing out that Elixir was not even a gleam in anybody's eye when Damien wrote this criticism.
That said, I would say most everything that Damien says here and is not already labeled as fixed remains an issue as written. Erlang is an exceeding conservative language community, from its telecommunications heritage, and its syntax has hardly budged from when it was first written.
I wonder if they're less likely to change now that Elixir is a thing. The community won't push on them to change as hard, as the community will move to Elixir. However, they still benefit greatly from the Elixir community as seen by OTP 20 and OTP 21 bringing great benefits from the Elixir community leaders.
I’m skeptical. It seems more likely a new, larger community will form (probably has formed) but I think anyone sufficiently dedicated to have used such an obscure, weird language prior will stick with it.
(I may be projecting a bit, but as someone passionate about Erlang I have minimal interest in Elixir.)
