Google just made a huge company shakeup. Here's who's gaining power.

• Google is merging more parts of the company in an effort to move faster in AI.
• Google's DeepMind chief has gained more power, while the head of Pixel will also oversee Android.
• The changes put more firepower behind some key Google products, and could help it launch faster.

The Googleplex is in flux.

CEO Sundar Pichai announced a series of re-orgs in a memo to staff on Thursday, and — surprise, surprise — Google says it's all happening because of artificial intelligence.
