Exactly how do you propose that humanity will overcome the limitations of communication? What kinds of situations are you talking about, and what means?
For me, there are two roads, one that we can use right now and another that we can't.
The first is just reading, watching, comparing, etc a lot (with lots of information). Getting very good at doing these things. There is a lot of information in the subtleties.
For example, if you have a post saying that a person had "stream entry".
Based on that post alone, maybe you can't be sure if he/she got SE. But with 10, 100, 1000 posts, some videos, etc, you can get a pretty good idea.
The same with books. You read one, two, three, 10, 100 different books on meditation, eventually you get the idea of what can be accomplished and how.
Repetition also works (like Daniel's video repeating again and again what is AP).
Also, there is some "weighting". Basically, you put more weight to books or posts or people that you think know what they are talking about.
Weighting is very difficult to do.
So, basically, tons (really tons) of information with lots of repetition.
The basic problem with this approach: it takes a lot (a lot) of time and effort. And still it's not perfect. Different people reading 1000 posts about about a person can get to different conclusions about SE.
It's also personal, once you read a 100 books on meditation, you get a clear picture, but you can't transfer what you know (other than telling him/her) to read those books.
The same with practice. With a lots of hours of practice, you get a clear picture of what practice is, but again, it's personal and can't be transfered.
So, this approach is for each one of us, to get the world to communicate with us and build an idea about something.
We can do this now because of the internet (before internet information was scarce).
The automation of this approach is simple, a machine that reads all the books, and, by reading what you post, your photos, your history, etc, build your "ideas", etc.
Machines can read text and view video a lot faster than we can.
The second approach is by sensing what's happening in our heads when we meditate, think, etc. Literally, neuron activity.
Coupled with some sensors of heart rate, pulse, movement, endorphins, etc.
This approach is the most accurate, but it is some years away.
To sum it up, we don't need a Unified theory of meditation. There are lots of them for us to read, analyze, try (practice) and build our own.
It does require a lot of effort though (a lot).
Or we can wait for technology on the second approach (mind reading) or the extension of the first (a machine that reads and understands and, by reading all books, all posts, viewing all videos on meditation) can build a unified theory of meditation.
They are some years away (not so many as people think as progress is exponencial).
