Why is there always someone who needs to read things in like this where nothing exists?

It's somehow very funny to me that we are talking about data transfer (QUIC) but that what happens at "level 8" of the OSI stack can also be complicated depending on what system level 8 runs.

There is no Level 8 as such. Everything happens at the application level i.e Level 7.

Level 8 is a joking way of designating the user. Also refered as "the layer between the keyboard and the screen".

Between keyboard and chair, surely?

PEBCAK, "Problem exists between chair and keyboard"

I think they meant the person and who they are as "level 8".

In other words, if you have this communication protocol, when it reaches level 8 the message might not be delivered or be misinterpreted based on the person. For example in this thread with some people seeing this as racist, some people see it as nothing.

Because those people have a racist mental model of the world.
