What is Google's business model for Tensorflow? also why did Baidu develop PaddlePaddle
<p>I heard Google has over 100 engineers working on Tensorflow. So, what does Google gain from distributing this expensive engine for free? Will Google later charge corporate Tensorflow users? ?</p>

<p>What is google’s plan for Tensorflow? will it be free forever? like a deep learning version of python?</p>

<p>Some people tell me it's to reduce new employee training time. If so, why did Baidu develop it's own deep learning library when that means they should spend extra time training it's employees who are used to using Tensorflow, how to use Baidu's deep learning library </p>
