The problem people have with Google and their PR campaigns is that Google isn't actually bringing out any projects to make the world better, they are just talking about them. It's all still in the labs. Over the last 10-15 years, Apple has released iPods, iPhones, and iPads. Products that profoundly changed and made a difference in people's lives.
I haven't seen a single industry Google has completely revolutionized like the iPod, iPhone, and iPad in the same time frame. The last industry Google completely revolutionized was search and the last time they did that was in the 1990's. You can't buy a Project Ara phone, you can't go to a car lot and buy a driverless car, and Google Glass is by almost all accounts a poorly thought out project and at $1500 a ridiculous price.
There is absolutely nothing special about showing off unfinished ideas that you can't seem to get right. All big tech companies have some really cool "Projects" in their labs that will blow your minds based on what's possible. Because that's the easy part. We put a man on the moon over half a century ago so that doesn't mean much. Google seems to be the only company that wants to show off these projects as if they have actually accomplished something. Even though lots of big companies have this stuff in their labs as well. It's all just PR.
Google can't ever seem to put out a great new innovation that completely changes an industry the way Apple does with products like the iPod, iPhone, and iPad. They have revolutionized the way ads are put in your face and bringing down privacy standards though. I'lll give them that.
