I feel like jobs where you can constantly rely on your already acrued knowledge are rare. Or maybe it’s just me and I work in fields where I have to learn new technologies constantly?

Recently I’ve been doing a lot of OCaml and it’s been tough as there’s very little on stackoverflow. Every time I have a question I have to spend a lot of effort looking for the answer instead of relying on someone before me having the same problem and posting the answer online.
