Good points, Carlos, but "imagin[ing] a technology that explores the meaning of what you write" is not so difficult. Other people already explore the meanings of things we write, and give us feedback about them; so to have a computer program do so is just an extension of that. Grammarly is just a good, inexpensive substitute for having a human grammarian check our writing in real time. Similarly, having an intelligent meaning checker would be really useful, but I think that is still fairly far off for most of us.

While we are alive, our brains grow incredibly intricate networks of ideas, only a small fraction of which we ever express in writing. So, after our biological brains die, another person or intelligent computer program is not able to model the entire stricture and function of our biological brains only from the written records we have left behind. That's why disciples of a human teacher always diverge from the master's teachings; an intelligent computer disciple would be no different. Our individual human consciousness remains tied to our biological brains.
