Definitely agree. Most teams don't choose a language for purely rational reasons, and we're not pretending we did.

We like OCaml, it makes us excited to build. We know the language deeply, which means we can reason about performance and behavior before we run the code. We can onboard new engineers quickly because the type system forces clarity.

The runtime is simple enough that we can predict what it's doing. So yes, part of it is that OCaml feels good to use. But that feeling comes from years of watching it make complex systems simpler to reason about, not harder.
