I think they all connected, for example with added lambdas they also added streams, so collections library now allows to do the same thing using old iterators or new streams APIs, and somehow those APIs are not compatible, it is not easy to produce stream from iterator.

Iterator is a very simple API that lots of third party code implements, but streams rely on spliterators for concurrency. You can sort of get a spliterator from any iterable and make a stream, but it will probably do all work sequentially.

which I never seen anyone uses and it makes everything more complicated

they probably should've have some ParallelStream interface
