>Today Google's eight rules for managers is basically a cross between HR and a life coach.

Is Google something to aspire to? They got early into a very lucrative market and have basically been milking it for decades. Good for them but luck isn't reproducible. Their ability to deliver new products is so bad it's literally a joke. I can't even remember any viable new product from them in the last decade (the 10th iteration of chat doesn't count). In terms of productivity they were known as a rest and vest company. Great for engineers but I can't imagine it's great for a company without a near infinite spigot of money.
