SegWit has just been activated! Why can't you just wait for a few months to go by in order to judge on whether or not people are really making use of SegWit transactions? It makes no sense to jump in and start saying that people don't care about SegWit. Let me put it like this -- how are you going to act in the coming days or weeks? Will you make use of SegWit, or just remain using Bitcoin as if nothing has changed? I definitely will start moving all my funds in order to benefit from what SegWit has to offer. I only don't see any point into rushing things, and so are others likely thinking as well.
We already have litecoin... and almost no one uses it. Bitcoin Cash or segwit2x might be the future, but Core shitdevelopers don't agree with 2x, guess who'll wins (hint: core won't).
