I work with Scala professionally. I often feel its type

And how long does that code take to compile ?
type inference is not magic, it's a search for a pattern over the
syntax (sub)tree.
Hence it can have quadratic time/memory complexity.
Additionally it's harder to prove sound, i.e. there is more
potential for undetected bugs,
As well as making it more surprising when the inference fails.
