Some notes:
- the actor model, along with the Akka implementation, has nothing to do with functional programming; and it isn't orthogonal either, since an actor's mailbox interactions are definitely not pure, with actors being stateful and at the same time non-deterministic; in general if you place those in the same article, there's a high probability that you never did functional programming; and if you did actual functional programming (as in programming with mathematical functions), then you wouldn't want to go back to a language that makes that impossible ;-)
- Akka actors are not the only game in town for processing data, you can also use Finagle, FS2, my own Monix and even Akka Streams; And yes, concurrency often requires multiple solutions because there's no silver bullet and Go's channels suck compared with what you can do with a well grown streaming solution
- Scala's Future are not meant for "hiding threads" and 1:1 multi-threading is actually simpler to reason about, because if that fancy M:N runtime starts being unsuitable (because lets be honest, most M:N platforms are broken in one way or another), then you can't fix it by choosing a more appropriate solution without changing the platform completely
- Your devs are maybe lazy or maybe they don't give a fuck, but given that you're supposedly dealing with concurrency in your software, if those developers struggle with a programming language, then it's time to invest in their education or hire new developers, because the programming language is the least of your problems
- Paul Phillips still works with Scala and he most likely hates languages like Go, so when you mention him or his presentation, it definitely cannot be in support of Go
