Ya in my mind, executables that do one thing well and are connected by pipes is one of the most proven models for getting things done. Even relatively nontechnical people can write shell scripts, batch files and macros that take some kind of data from a socket/file/pipe, pass it through a bunch of black boxes and spit out an answer. This is very similar to the Actor model and is much simpler to reason about than the shared state threads of languages like Java. Optimizations like copy on write can eliminate most of the overhead of sending data between processes. Here's a quick overview of how the Actor model is better than shared state (mainly by avoiding locks and nondeterminism): https://doc.akka.io/docs/akka/2.5.3/scala/guide/actors-intro.html https://doc.akka.io/docs/akka/2.5.3/scala/guide/actors-intro... And just as an aside, I haven't fully learned Rust yet but from what I understand, the borrow checker only applies to mutable data. If you write a fully immutable Rust program then you can avoid it altogether. So to me, this is a potential bridge between functional and imperative programming. It also might apply to monads, since (from what I understand) languages like ClojureScript can run in one-shot mode where all side effect-free code runs completely and then the Javascript runtime suspends execution, only starting it again once new data is ready. This might also be a bridge between functional and imperative code, because I've found monads to be one of the weakest links in functional programming and I've never quite wrapped my head around how they work or if they're even a good abstraction. Maybe someone can elaborate on them! In short, the goal here is to reduce all concurrent code to a single thread of execution that is statically analyzable as much as possible. So a typical C++ desktop app may not see much benefit from this, but anyone who has found themselves in Javascript callback hell can certainly appreciate the advantages that async/await provides, since it more closely approximates the message passing of Erlang/Go, which is more similar to shell scripting. If we had a "perfect" language that optimized all code to be concurrent as much as possible, for example by converting for-loops into higher order functions like map and then running them on separate threads behind the scenes, then we could offload the wasted work currently done by humans onto the runtime. So that would mean that instead of writing programs that, say, access remote APIs, cache the data somehow, remember to invalidate it when the source of truth changes, etc etc etc, that complexity instead could be reduced to a dependency graph that works like a spreadsheet and updates all dependencies when something changes. This seems to be where the world is going with reactive programming, with a lot of handwaving and ugly syntax because it's reimplementing old concepts from Lisp etc: https://en.wikipedia.org/wiki/Reactive_programming https://en.wikipedia.org/wiki/Reactive_programming Sorry this got a little long, I could ramble about the downsides of programming in these times for hours.
