There are two layers when it comes to information (or knowledge).

First layer is nuance. It is the currency of thought processes in our brains. It is real, useful and effective.

Second layer is the text (or langauge). I call this text but it can be anything like written texts, verbalized acoustic waves, drawings, pixels on computer screens. They are tangible and storable, they can be transferred between individuals. But they are not directly usable, they are also low in efficiency.

We have to convert the second layer into the first layer for the second layer info to become useful.

|nuanced thinking/thoughts|-|text|

So what we do as humans is we try to exchange info. And when we do that we are really just trying to exchange what is on the first layer but because nuances are not yet directly transferrable (that is why I really want a thought sharing machine) we have to use the second layer info. And this is where the info loss happens. See:

1st layer of person A (A thinks) -> Second layer of Person A (A encodes the language and talks) -> Second layer of Person B (B listens and decodes) -> 1st layer of person B (B perceives)

There’s a big incentive behind reducing this info loss.
