There are 3 ways an adversary can read your encrypted message:

1. Somebody gave them the key, either deliberately or by mistake.

2. The algorithm is faulty or weak.

3. The adversary has the resources to do a brute-force attack. That relates somewhat to #2.

All of these can be avoided, if you do it right. Sometimes people don't do it right.

If authorities want access (to communications), and the messages are not securely encrypted, they will find a way.

It's not difficult to encrypt data such that others will not find a way. But sometimes people don't.

The UK government is a vague organization.

Do you know who that is? Can you trust them with your information? Would you send them a copy of every message that you send anybody?

No, no, and no.

The military uses encryption that follows the same rules as other encryption.

They are generally more careful to make sure their crypto systems are secure. In theory.

The German military had a really good crypto system in WW2, and it was broken partly because humans made mistakes.

A back door literally means a third party can read your message.

In theory, it's a good third party, but there's no way to be sure of that.

There's no such thing as a secure back door.

A back door is code for "other people can read your message that you thought was secure".

People in the government who say messages must be encrypted in a manner such that the government can read them doesn't seem to understand how encryption works.

Encryption keeps anybody from reading your messages. That's just how it works.

Do you understand that the shareholders own the company?

If you own a coffee shop, are you going to run it in a way that makes you happy, or some other way?

If you want to transport water or gases from Earth to Mars, the amount of mass necessary to make a minimal atmosphere or any kind of ground water is staggering and impossible.

Steering an asteroid or comet to collide with Mars is also quite a trick, and finding one that's headed roughly for Mars could take quite a while.

These things are great for a sci-fi story, but in the real world we have laws of physics that we must answer to.

I thought it was so they didn't have to commute to work.

Why does anybody, including Brazil, care what accessories Apple provides with a phone?

Was Apple deceptive? Did they show a charger in the picture on the box?

I feel like I'm missing something here.
