It's not impossible to solve those types of problems if you prepare ahead of time. I think that problem just requires dynamic programming/memoization, which is one of the things you're told to study beforehand.
I thought the fact that messages and photos are kept was a feature. As in, I can scroll back a decade in my photo albums and look at pictures from my high school graduation.
But that's still Google providing the advertising. In what way is your search history not contained to Google when an advertiser asks Google to display text ads with your content to people that are interested in X, Y and Z?
I can think of a few very expensive ways, but those are also ways in which Google is allowing erosion of their competitive advantage by allowing that information to leak. That, by the way, is why I don't feel particularly paranoid about Google sharing my information everywhere. Google is strongly incentivized to keep it closely guarded so other people can't monetize it in ways that cause Google to lose out.
I think it's a bit misleading to simply say "LSD is great and you should try it". It can be interesting, but also can be scary as fuck, and you should be in a good place mentally before trying it.
"Snorkeling is great and you should try it," is a similar statement I might make with no qualifications or equivocation from you. Many pleasurable activities have attendant dangers that you should be aware of before engaging in them. Drugs are no different, except we surround them with the stink of moral judgment and refuse to educate people on how to use them safely.
The difference is most people snorkeling for the first time do it with an instructor who is very much interested in their well-being. I don't think the guy who sells you LSD is gonna lose sleep if you happen to develop a lifelong mental condition.
I read an article yesterday about micro-dosing LSD at a level where no hallucinations appear, but a boost in energy and creativity is felt. Like a different kind of coffee that doesn't wane after only two hours.
I really don't know. I assume that you are correct that it has been normal at various times throughout history - the railroads come to mind for sure.
But it seems to me - and I have no special insight on this per se - that technology companies have dramatically increased their reliance on insider contacts in government in the past... I dunno, 5 years? Something like that? Maybe 10?
I sat through pitch week at BluePrint in NYC and I was absolutely floored at how many companies (seriously almost every single one) openly described the advantages they thought they had as a result of odd or even outright unethical health-care 'regulations.'
