I do hope this will be addressed once we arrive in Baldurs gate. I find the subject difficult to judge without having the full game.

What I haven't seen anyone mention in skimming through the last page is... well. The tendencies of mindflayers to form a hive mind. Even lone mindflayers who break free from the elder brain's subjugation are destined to evolve into elder brains themselves. (If I understood that lore video?)

You know where this is going :P

In absence of any evidence otherwise, I like to sit on my conspiracy theory. Mostly because everyone thinking "wow, I'm feeling so fine and myself right now!" while under the thrall of some hive forming instinct is hilarious.

For the record, I don't actually /think/ it's true. But, it's how I entertain myself when Tav has 9 charisma.
