So basically: "yes, I know AI is actually completely and totally useless and a net negative on the world just like you say it is, but I can imagine that things will suddenly turn into the sci-fi ultraverse for no reason so therefore you're wrong."

"The Rules of Crust

Every function is unsafe. No references, only pointers. No cargo, build with rustc directly. No std, but libc is allowed. Only Edition 2021. All user structs and enums #[derive(Clone, Copy)]. Everything is pub by default."

Great, please make all the software even slower than it already is. I am overjoyed to have to purchase several new laptops a decade because they become e-waste purely due to the degradation of software performance. It is beyond ridiculous that to FP programmers daring to mutate variables or fine-tune a for loop is an exceptional scenario that you don't do "unless you have to" and which requires "knowing what you're doing". Do you know what you're doing? How can you be a software engineer and think that for loops are too difficult of a construct, and that you need something higher-level and more abstract to feel safe? It's insane. Utterly insane. Perhaps even the root of all evil, Code Golf manifested as religion.

Well, we already know that no pure FP language can match the performance of a dirty normal imperative language, except for Common Lisp (which I am happy to hear an explanation for how it manages to be much faster than the rest, maybe it's due to the for loops?). And another comment here already mentioned how those "significantly slower" scripting languages have a healthy dose of FP constructs -- which are normally considered anti-patterns, for good reason. The only language that competes in speed in Rust, which just so happens to let you have fast FP abstractions so long as you manually manage every piece of memory and its lifetime, constantly negotiating with the compiler in the process, thereby giving up any of the convenience benefits you actually get from FP.

Well, this is probably why functional programming doesn't see a lot of real use in production environments. Usually, you actually do have to care. Talk about noticing a performance regression because I was simply appending to an array. You have no idea what performance regressions are happening in ANY line of FP code, and on top of that, most FP languages are dead-set on "immutability" which simply means creating copies of objects wherever you possibly can... (instead of thinking about when it makes sense and how to be performant about it)

You don't really think that functional languages aren't appending things, using temp vars, and using conditional logic behind the scenes, do you? What do you think ".filter(node => !node.isHidden)" does? It's nothing but a for loop and a conditional by another name and wrapped in an awkward, unwieldy package.

>which introduces a performance regression from having to periodically grow the array

This is simply ridiculous, do you just believe that the magic of Lisp/FP allows it to pluck the target variables out of the sky in perfectly-sized packages with zero allocation or overhead?

  o_node := graph.GetNodeByName(name)
  var ret []string
  for _, node := range o_node.connectedNodes() {
    if !node.isHidden {
      ret = append(ret, node.name)
    }
  }
  return ret

First of all, you shouldn't be using Go, because it's not the language where you do those kinds of things.
