Imagine waking up tomorrow with the solution to the Voynich Manuscript.

When a solution with some promise is put forward, this will become clear. 

As someone who has received proposed solutions on a regular basis for years now, I use exactly this criterium to decide if any of them are worth a closer look.

The key words are "solution" and "promise". I really don't care about solutions that say the text is meaningful, yet don't actually include a specific mechanism to translate the text. Most of the recent 'protocols' and 'frameworks' miss the boat for exactly this reason.

Then, what is the meaning of "promise"? 
For me this is something, anything, in the proposal that goes in some way to explain the key oddities of the Voynich MS text. Or even just potentially do that.

When a solution with some promise is put forward, this will become clear. This has happened several times in the past, even though so far, none of those theories have managed to live up to the expectations. (Quite on the contrary).

Based on my own criterium, this has not yet happened. The only cases where I still decided to take a closer look were when at least there was nothing contradictory, for example when the proposal suggested the source text is Arabic. I do not know enough about that language group to decide either way.

What remains true is that such an initial promise is no guarantee that it will live up to the expectations.

The real problem here is that it is a huge stretch to compare Voynich MS 'research' to any form of academic research or historical discoveries. 

In every field, you have to start by learning. You need to read a lot and even that is rarely enough. You need instruction and you need feedback (tests). 
That is not the case with the 'vast majority' (deliberately vague term) of Voynich solution proposers here.

Oddly enough, LLM's have read a lot, keep on reading, and are likely to catch on. Sadly, the people using them rarely know enough to be able to properly grasp and judge their output. 

Ventris often comes up, but it is also a huge stretch to compare Voynich MS newcomers to him. 
Ventris knew Greek. He spent a significant amount of effort studying earlier research on the topic.
He had a theory (Etruscan) but gave it up when the data pointed him in another direction (Greek).

Also, his case is not the norm. It is a major exception.
