How Can Digital Beat Analog?

I studied computer engineering in the late 80s. Though digital electronics had been around for a long time, it still retained some novelty.
As budding engineers we were in a dilemma: Why was digital electronics considered so cool and why was analog electronics considered seriously yesterday?
Of course there was no doubt in our mind that digital was the way to go, but the question still remained: Why?
Was it not true that in analog transmission, you could transmit any value, while in digital transmission, it was typically about binary transmission. And binary transmission means a bunch of zeros and ones. What could be the fun in that?
For instance in analog transmission, if I wanted to transmit the number 254, I would simply send it as 3 digits, a two and a five and a four. But in digital, specifically binary transmission, it would have to be 8 digits, i.e. 11111110, i.e., a series of seven ones and then followed by one zero.

I have been talking about binary transmission when talking about digital, because they are not the same thing. Binary transmission is just one type of digital transmission. There can be many others. For instance there can be trinary, which […]
