Opinions on Dart's Isolates?

I’ve been looking into Flutter a bit as a platform for phone apps, and that got me looking into the Dart language. Their approach to concurrency feels awful familiar, with “isolates” looking a lot like Erlang processes. It’s actually pretty cool, nice and clean, albeit wrapped in some OO noise. I imagine, though don’t know, that they were influenced by Erlang/Elixir, although I suppose something like parallel evolution of the Actor model could be responsible as well (sharks and whales look a lot alike).

Anyway, I wondered what other Erlangers thought about it. You can find an overview here: [Isolates and Event Loops - Flutter in Focus - YouTube]
