Why would anyone settle for underpaid positions from an agency taking a 7% contract cut, and purging CVs from any external firm also contracting with their services.
Most people figure out this scam very early in life, but some cling to terrible jobs for unfathomable reasons. =3
If folks expect someone to solve problems for them, than 100% people end up unhappy. The old idea of loyalty buying a 30 year career with vertical movement died sometime in the 1990s.

In this type of situation, the fundamental issue is that making progress depends on many people acting in unison to increase their bargaining power, which is (a) hard to arrange even if everyone who acted this way would benefit, and (b) actually may be detrimental to some people (usually the high performers).
I agree it is nearly impossible to alter the inertia of existing firms. Most have entrenched process people that defend how things are done right up until a company enters insolvency. Fine if you sell soda or rubber tires, but a death knell for technology or media firms.
In my observations it is usually conditioned fear, personal debt-driven risk aversion, and or failure to even ask if the department above you is really necessary. These days, it is almost always easier to go to another firm if you want a promotion. =3
You know you could just define the verified specs in lean and if performance is a problem, use the lean spec to extract an interface and tests for a more performant language like rust. You could at least in theory use Lean as an orchestrator of verified interfaces.
Strong agree. OCaml's compiler is sofa king good at catching and preventing real bugs that the agents accidentally introduce here and there. It's the same as with humans, except the agents don't complain about the bullshit reasons humans don't like OCaml. They just crank through and produce high quality output.
It's still in beta but I repackaged Descent Raytracer (a remaster of Descent (1995) made by students at Breda University) to be launchable on macs with Apple Silicon (ray tracing reqs M3+).
What a weird coincidence. Literally today I started building a fully keyboard driven MIDI sequencer in Rust. I was originally going to build it as a TUI but then decided against it because I wanted to have more control over the UI, so I'm building it as a pseudo-TUI with Bevy. But the idea is very similar, I'm approaching this project as a "vim"-like editor but for MIDI editing.
Here's my take. It helps you enforce properties about your data. Didn't mean to make this response so long, but alas.
(*
Quick note on notation: I will use "double quotes" when referring to _values_ and `backticks` when referring to _types_.

(*
Think of this as an interface. It defines the shape of a module. Notice that the interface describes a module that defines a type called `t`, and two values: "of_string", and "to_string", and they are functions with types: `string -> t`, and `t -> string`.
*)
module type ID = sig
type t
val of_string : string -> t
val to_string : t -> string
end

Below this comment is a module named "Id" that _is of type_ (in other words: it _implements the interface called_) `ID`. Due to the explicit type annotation (Id : ID), now from the perspective of anywhere else in the code, the exported interface of the module "Id" is `ID`.
Modules only contain two things: `type declarations`, and "values". Values are your primitives such as 1, '<', "hello", but also composite such as (fun x -> x + 1), (Some x), f x, { foo = "bar"; baz = 42 }, and even (module Id) (yes! modules can be values too!). Type declarations tell the compiler . Anything which is a value _always_ has a type that can _usually_ be inferred.
No type annotation is necessary when the compiler correctly deduces the type of your value through static analysis. For instance, in the module below, "of_string" is deduced to be of type ('a -> 'a). The ' on the symbol 'a signifies a "type variable", and it means that it can be filled in with any type. For instance (t -> t) and (string -> string), but not (t -> string) or (string -> t). For those it would have to be of type ('a -> 'b). We cannot deduce this type, however, because our implementations do nothing with their inputs besides return them. Since nothing is changed, it's always the same type.
Now, can you spot the pink elephant? Notice how the "ID" interface from above defines "of_string" to be of type (string -> t). How can this be possible? It's because we gave the compiler a hint when we said `type t = string`. This says that a "value" of type `t` is backed by a value of type `string`. If something type checks as `t`, it also type checks as `string`.
So, we could reason through and say ('a -> 'a) can be instantiated to (t -> t), but `t` is also equal to `string`, so we can mentally imagine a hypothetical intermediate type... something like ({t,string} -> {t,string}). This type and type equality is visible _inside_ the module. But when the `ID` interface was applied over the `Id` module as in (Id : ID), this has the effect of hiding the type equality (the fact that `type t = string`) because in the `ID` interface we define `t` without an equals sign: `type t`. This forces us to _choose_ a concrete type to expose externally, even though the type is less general than what the implementation sees.
NOTE: OCaml doesn't use parens for function definition or application. Compare this OCaml code against its Python equivalent.
> let hello_world h w = (h, w)
> let h, w = hello_world 1 2
vs.
> def hello_world(h, w):
> return (h, w)
> h, w = hello_world(1, 2)
*)
module Id : ID = struct
type t = string
let of_string s = s
let to_string s = s
end
let main () =
let s = "abc123" in
let id = Id.of_string s in
(* NOTE(type error): because the built-in "print_endline" function is of type (string -> unit) and not (Id.t -> unit) *)
(* NOTE: if an expression returns unit, you don't need to create a let binding for it. You can simply tack a semicolon to the end of it if you need sequence another expression to follow it. *)
print_endline id;
(* okay *)
(* STDOUT: abc123 *)
print_endline (Id.to_string id)
;;
main ()
You could imagine implementing this pattern of defining parsers such as "of_string", "of_bytes", "of_json", "of_int", "of_db_row", "of_request", for any piece of input data. You can think of all of these functions as static constructors in OOP... you take in some data, and produce some output value: e.g. "of_string" takes in a `string` and produces a `t`.
Now, if you have a bunch of "values" of type `t`, you know that they _only_ could have been produced by the `of_string` function, because `of_string` might be the _only_ function that ends with `-> t`. Therefore, all the values maintain the same properties enforced by the `of_string` function (similar to class constructors in OOP). With this, you can create types such as `Nonnegative.t`, `Percent.t`, `Currency.t`, `Image.t`, `ProfilePicture.t`, and parsers from another type to the newly minted type.
The compiler can help you enforce these properties by providing guardrails in the form of static compiler checks (these checks are run _before_ your code can even be compiled). If I have a value of type `Nonnegative.t`, then not only do I not need to validate that it's not negative, I also don't have to validate that it's not negative everywhere else that values of that type are used -- the validation logic is baked into the constructor. Parse, don't validate.*
Joy is probably an improvement on slog, but one person's joy is another's hell. I've inherited a lot of joyful projects that were an awful fit for continued maintenance because joyful meant using new, unproven, and unstable technologies.
I have experienced many identical situations. Some people just love to tinker and over-engineer for the sake of stretching a muscle. It's unfortunate when that sneaks into a prod system that has to be maintained by others.
