Honda president Takahiro Hachigo has just announced that Honda will complete development of fully self-driving cars by 2025.

But aside from just being solid, filled-in shapes, the real treat in the Pixel's nav bar is the Google Assistant animation that gets activated by long-pressing the home button.

Technology can move really fast. Just consider the format for which we consume videos and movies, which has transformed from film reels to VHS to DVD to Blu-ray to steaming with nothing physical at all.
