Starline, really? While this sounds like neat technology, I'm not sure if it has mass-market potential in the same way that VR/AR does. Is every company going to be clamouring to outfit their meeting rooms with Starline units? Is every kid going to want a bulky Starline set in their home/bedroom? How much is it going to cost relative to the sort of cheap mass-market headsets that are likely to be available in 5 years time?

Remember, Google is a company that shuts down even some of its relatively successful products, so it's hard to imagine Starline ever succeeding as an actual Google hardware product.
