Depends how many false positives and false negatives, but if there's 4% of false negatives and there's, say, 1% of the tested population that has the disease, then even a positive test may mean you have only 20% chances of being actually positive.
(someone double check my math, but the general idea stands, I think)

The author is interviewed in the documentary.
Tom Wolfe's The Right Stuff is also great to understand the test pilots from which most of the astronauts were picked.
Amazon sells almost 200bn of goods each year. Even if a tiny fraction of those are problematic and slip through the cracks, it'll seem like a lot to observers. Doubt they can get it down to zero, no system is perfect, and there are too many attackers trying to game the system.
It's a price to pay for all the benefits of the open platform model.
Corollas and Civics can last forever.

In my experience, Guetzli is a lot slowly than mozjpeg, but tops up at much higher space savings when the conditions are right.
If you're interested in compressing JPEGs without quality loss, there's a free Mac app called ImageOptim that can handle JPEG, GIF and PNG. It has Google's Guetlzi, so on some JPEG you can reach 20-40% compression without any loss of quality that I could detect (and sometimes lower levels around 10% on images that are already well compressed or smaller resolution).
Boards full of non-shareholders tend to prioritize the paycheck they get as board members, so they tend to not want to rock the boat or get into conflicts with mangement.
Those that are shareholders first tend to have a bigger incentive to confront or fire management if they start doing things that are bad for shareholders.
Mine's in my pocket when I'm at the store.
Even if Apple brings back the cash and dividends it out, that's more money in the pockets of shareholders, which are pretty much everybody with an index fund, pension funds, mutual funds, etc. That can't hurt the US compared to leaving the cash abroad.
Forecasts are created by financial analysts working for big banks and brokerage firms, not Google employees.
Some exchanges have 150 types of orders that are mostly undocumented and unknown to most regular players, created specifically so that HFT can not do what they publicly appear to be doing, or take incentives without providing liquidity, etc. The public price that everybody seems is outdated compared to the private prices that HFTers see, so they can risklessly front-run people because they already know if a price has dropped or rise, etc. All that stuff isn't just fast market-making.
