Is there a reason to emulate google if your company is not trying to become an adtech behemoth? Google just sells ads, and has not originated a successful product besides search. They have an endless stream of failed pursuits, and so this could be a guidebook on inefficiency and exploratory tangents that don't produce value. That's why they laid off 12,000 employees since this guide was written. If anything, companies should try to follow Apple's workflow, which hasn't had layoffs and has a track record of elegant software that produces value in new areas.
