I took a course that was all about the historical progression of science as a discipline since the early 1800's, and it really opened my mind to how much I didn't know about science. I really think that a course like that should be taught to students BEFORE they start taking high school science courses. This would provide a historical context for the content of science courses and, I believe, make it a lot easier to digest the material in a science class (for the reasons the author suggests).

Any toothpaste with menthol (pretty much all of them) contain a local sedative, it's just not addictive

True, but I bet that the NSA could force WhatsApp to issue certificates for fake keys. Obviously can't do that without being noticed, but they could still use it to spy on specific users if they wanted.

WhatsApp wouldn't keep the private keys. That being said, this system could still be hacked - when the clients exchange public keys, you insert yourself in the middle, provide your own public keys to each client, and mediate between the two clients, which gives you access to the unencrypted messages.

The thing is, WhatsApp is not just refusing to comply - they can't comply, since they don't retain message data. In addition, now that all messages are encrypted end to end, it will be impossible for them to comply in the future.
