I’m aware. But if you read my explanation a little more carefully, you’ll see that the argument being made is that this de facto constitutes a form of lossy compression.
The easy comparison is that a JPEG does not store an “original” image, but it contains information that can be used to almost perfectly recreate that image, with the help of a little math.
If the same argument can be said to hold true of LLMs - and yes, that is very much a load-bearing “if” - then they would constitute a form of lossy compression.
