And what is the semantics of parallel on an infinite stream, you split the infinity ? It is perfectly sensible. We can take infinite generators and parallelize them easily enough; see the implementation of Iterators.spliterator(). The only challenge is "how do you make it stop", if you care about that. Which is why we're talking about cancelation.

You are saying that you have a way to limit the stream, why is it different from parallelStream.limit(...).into(new ArrayList<>).stream() with limit using the semantics suggested by Sam.
