No matter how much you optimize your schema and your queries there are limits to what one machine can handle. Depending on what your application or business needs are, this may happen MUCH sooner than a billion users. For many, merely tens of millions of really active users are enough to exceed these limits, and when you are a startup trying to grow and add features it is easier said than done to ensure that every piece of code you release is so perfect that you will not rock the boat at all, since one minor slip effects EVERYTHING. At that point your choices are custom sharding (expensive, painful, error prone). Or horizontally scalable NoSQL. Personally, I would just choose NoSQL from the start. It is not harder to use, and you have a lot more wiggle room to respond when you want to release features quickly and iterate over them to improve performance if you decide to keep them. And yes, you can use functional sharding and multiple relational databases, but sooner or later if you are successful, you will hit the same problem.

And I might add that one of the most painful parts of migrating away from relational databases after you are already huge and bursting at the seams is that usually folks will have relied on the transactional consistency they provide for all the app logic and business processes. Suddenly wanting to change all that code to handle eventual consistency is not trivial at all, but if you were doing it all along because you started out that way... fewer pains.

Actually, more than you think should probably use NoSQL. It isn't really any harder if you build it that way from the start and if your startup happens to get gigantic you won't have a relational database to migrate away from as one of your problems. You'll still have problems though, and even with NoSQL you need to "do it right" or it will still have issues when it gets huge.

Technically most phone GPS apps would be illegal even if you weren't entering data since they get the map data over the internet. This whole nonsense is a slippery slope, why is it safe to use the car's built in GPS, but not the phone? Should it be illegal to adjust your climate control knobs? What about chewing gum? You can't legislate away stupidity.

Those are general requirements. The chances of someone with 20/50 vision actually being made a fighter pilot as opposed to some other role are basically zero unless they have absolutely amazing abilities otherwise. They'll tell you anything you want to hear during recruiting, but you have almost no chance no matter what they say.

Many many people desire to be fighter pilots. The problem is not a lack of people wanting to sign up. The problem is that the USAF is highly selective about who can be a fighter pilot. You need to meet all sorts of physical requirements, then you need to meet very high academic standards, then you have to meet a whole bunch of psychological/personality requirements, etc, etc. By the time they go through the pool of applicants there is nobody left.

You shouldn't assume BMW and Mercedes drivers paid a lot for their cars. I paid only $16k for my used Range Rover. Way better vehicle than other comparable used vehicles and pretty much the same price. It is 10 years old still looks brand new (despite harsh new england winters), there isn't a single rattle, the interior is still flawless (I clean it once in a while but I'm not a neat freak). Granted, someone did pay about $90k for it originally. I would love to thank them for taking the depreciation hit for me :)

The only way this might be true is if you are going really slow (i.e. walking/jogging speed). At 25 mph which most cyclists who are in decent physical condition are more than capable of riding, you won't be able to react as easily as you think. Far, far safer to ride with traffic the same as other vehicles and OBEY the traffic laws... it is unbelievable how many riders I see running stop signs and lights, making illegal turns, etc, etc... it is so dangerous. Just get mirrors to see behind you. Mount on handlebars and/or helmet.

One way to make your old car run better is to look up the price of a new model.
