There were dozens of individual announcements at Google I/O, but as the event wraps up, here are three broad themes that stood out:
1. No sexy new hardware doesn't mean there wasn't anything important.
It's easy to dismiss any big tech event that doesn't produce a really cool new gadget. And, certainly it's more fun when there is something new like Google Home and Daydream, both of which were introduced at Google I/O last year. But Google's main business isn't from selling individual products, but creating whole ecosystems. This year was about strengthening the fundamentals of Android and expanding its footprint in new markets, like artificial intelligence and virtual reality. Not sexy, but important.
