This book is a very important work that covers the complex business model and complex effects on the public of the big tech companies such as Google, Amazon, Apple and others. Ms. Foroohar illustrates the effects big tech has on government policy, tax compliance, labor, innovation, oligopoly status, data mining, data usage, data selling , crime control and so much more. All these topics come with both pros and cons. There aren't easy solutions and that's why we need to understand the far reaching effects of big tech so that we can have a productive conversation going forward how it is to be used and regulated.
