The way of controlling the servo is just one way to categorize it or compare it with other motors yes. But there are other characteristics that could be compared.

So a servo is not really a type of motor (e.g. DC, AC, brush, brushless, induction).

I don't find the 555 timer very intuitive to use. It seems more like a black box. Why not just use Op Amps, transistors, and FETs which are all easier to use?

If you need the functionality provided by a 555, you could build it from other parts, but this would increase cost and space. This is why it exists.

You're a beautiful man.

What is the easiest way to make a Servo. I think I saw a YouTube video where they used a 555 timer to control a motor.

Is there even a simpler Servo circuit?

I'm not convinced the 555 was 'controlling' the motor, I'd need to see a circuit to be sure, most likely it was just changing the average voltage seen by the motor.
The simplest servo is an op-amp and 2 resistors (an inverting amplifier is a purely proportional servo) Note that 'servo' has nothing to do with motors, it is just often used to control them. I use a lot of PI servos, which just adds a capacitor to the circuit in the feedback, but there's usually a more complicated feedback path as I'm not just controlling the output voltage, it's usually a current in something or a big voltage somewhere.
Here's a voltage controlled current source:

The load could be a motor

I know a lot of advances in electronics have been driven by porn. I heard that porn is really bad. Yet, electronics is used to transmit porn content in a massive scale. And corporations net massive profits from transmitting this content via satellite and cable, because the money is too good not to get a piece of that pie. Is porn bad, or is it a tool in the engineer's toolbox?

I can't think of any advances in electronics that have been driven by porn. Sure, porn may have benefited from the advances, but I don't think porn was the driving force.

Naaaaaaaaaaah, c'mon...

Some is good, some is bad.

Western civilizations enjoy freedom to exchange ideas and thoughts, regardless of what those things are (more or less... some countries do have legislation that limits free-speech, such as the hate crime laws in the UK). Those that lobby against porn are often in favour of clamping down on freedoms and are pro-theocracy. I can't stand such people.

Um... it's the internet...

You need to make a distinction between technology and the content the technology is designed to distribute. The internet is a massive collection of data over a global network with an incredible amount of content... music, television, films, art, games, moving pictures... almost everything you can think of is on the internet. Porn is just a particular type of content, so it should be largely irrelevant for your engineering studies (nice try ).
