Why is the Voynich Manuscript Still Undeciphered ?

[ReneZ]

For me, the reason why it has not been deciphered is at a higher level than the points in the first two posts here, for example: lack of context, lack of cribs.

The reason for me is that this text doesnt 'work'  like known ciphers. As a result, we don't even know if there is no meaning at all behind the text, a heavily diluted meaning or more.

Wondering what is the language assumes there is meaning and assumes that the language somehow is still apparent after the 'encoding process'. We don't even know if either of these is the case.

We have quite a bit of context. A relatively precise date and a rough idea of the region, but this does not help us because of the higher level problem.

There are plenty of good candidate cribs in the MS but they just don't work because of the higher level problem.

What would certainly help a lot (obviously) would be finding original notes from the author(s) / scribes.
It would be like a spoiler.

Edit: comparison:
I find it interesting to compare the Voynich MS with the equally undeciphered Dorabella cipher.
For this, we have an exact context. We know who wrote it, when, for whom. We even know that the reader was expected to understand it quickly (but that did not happen). The problem here is primarily that it is too short.
The Voynich MS on the other hand is very long. It is probably equivalent with 100 enciphered letters.
Then again, for modern AI techniques, it is quite short.
