That's how all of war works. Battles usually have lower casualties than a casual observer would guess, and those that do are usually remembered as bloody. You don't engage until you know you can win. If your enemy advances you retreat. The weaker side retreats until they can't, then they surrender or are destroyed.

If anti-carrier missiles have a longer range than the carrier's aircraft, then the carrier is in check. So now maybe you have to use a guided missile submarine and cruise missiles to destroy the anti-carrier missiles first. Maybe your opponent has a good anti-submarine force. But maybe your carrier's planes don't have enough range to hit the anti-carrier missiles, but they do have enough range to hit the anti-submarine force.

War is not rock paper scissors.

Unions would be okay if they were subject to the same market forces as their employers. But they're not, they're protected by reams of labour law. Unions are allowed to monopolize labour in an industry and force anti-competitive security agreements, which would be considered anti-competitive and illegal in any other contract.

Consider the infamous 'right-to-work' states. What does being a 'right-to-work' state mean? It means unions can't compel people to join. In Germany, for example, the decision to join a union is considered an individual decision, and workers have an equal right to join or not join a union; the right to free association, means you're also free not to associate if you don't want to. But if you disagree with your union in Michigan and want to opt out, good luck making that legal argument.

The SR-71 was derived from the YF-12 which was an armed interceptor.

Also, to cope with heat expansion the fuel tanks don't seal on the ground. It always has to refuel after take-off, so there's no point in filling the tanks. You fill it with just enough fuel to get off the ground and get up to speed (and heat).

In the US, generally the maximum penalty for killing someone is death, which I think most agree is more severe than 15 years.

As a matter of course, most people convicted of killing someone else don't get the death penalty, and neither is this man is likely to face 15 years in prison. Those are both the maximum penalty.

The thing about trends is they never end, until they do. Just because some people were wrong about Apple years ago, doesn't mean they're wrong about Apple today.

Apple may be extraordinarily successful, but its success is based upon a product line that is:
1. Almost entirely consumer driven, and
2. Incredibly undiversified.

That's an incredibly risky strategy. Most companies build successful long-term business by establishing well diversified product lines, or by building product lines and business relationships that establish long-term cash flow. Apple's bet their success on their ability to stay cooler than the competition. So what's a more likely scenario for 2022: that the world is still addicted to Exxon's oil, or that the iPhone 10 is still the hottest product on the market?

1920 x 1080 x 24fps is 50 million pixels per second. Recent CPUs from Intel top 100GFlops, which is 2000flop/pixel, and recent GPUs from NVidia are topping out around 4000Gflops, or 80,000 flop/pixel.

Throw in enough geometry and you can cause problems, but that's more than enough horsepower to draw a simple scene in realtime.
