I do not fear the rise of superintelligence.
I do, however, fear the rise of billionaires, organizations, and world powers who seek to use computing to maximize their power, influence, and control.

What is 1+1? Would an AI be broken if it gave an answer other than 2?
If you expect "2" you don't really understand how LLMs work. For at least two reasons.

try F# today folks, it comes for free within #dotnet sdk !Super easy to get started in vscode with Ionide extension or VS/rider , it’s the .NET ocaml great interop with C# in the same solution, use all the nuget packages you already know and love 💕 has scripting .fsx and REPL baked in

I got the feedback that the word "slowly" - even with quotes - is a bad choice because writing code manually isn't per se slow.
Absolutely true. I even wrote in the post that I think creating business-logic-heavy code is faster to write directly in code than going through a spec and an agent.

When I open my social media feeds, it's obvious: the age of writing code with our fingers is ending. LLMs can write code much faster.
But was it ever about the speed of code creation? I think not.

One thing that always gets me a while to get used to after not working in #fsharp for a while is the ordering
For those not aware, F# reads things in order, both in a module, and the file system. So the entry point for a program must be the last file, and in any module, the entry point is last.

It's kind of funny that due to AI/LLMs these days another metric to rate #programming languages on has become "token efficiency".
On the bright side - some of the beloved languages like #Clojure, #Ruby, #FSharp and #OCaml fared pretty well due to their expressive and compact syntax.

Why didn't I find this great feature of Rider earlier?
It makes initialising records so much easier.
And with a quick invocation of Fantomas, the record is reformatted to match our settings regarding { } alignment. We prefer the Aligned option.
