Google has an engineering culture that is biased towards chasing the next big thing. If you're not building something new and noteworthy then it's not valuable. This is good for Google as a business, but can hurt consumers by leaving them with dead and dying products. On the other hand, the web is powerful because it is ubiquitous, stable, and democratised.

So you take Google engineers, coach them and reward them for demonstrating impact through building new features. Change is good, stability is bad. Then you put them in charge of the web platform. The natural result is an avalanche of new standards and an inclination to discount the status quo.
