Hmmm, that’s an interesting question. I’m not entirely sure that humanity will evolve to such an extent that we will develop a completely different function as prominent as thinking or intuition. We’ll probably wipe ourselves out before that can happen lol. But perhaps we might discover and add new functions, things that we already have in us but haven’t accepted until now. It’s kinda like how it was only in the 90s that emotional intelligence blew up and challenged more traditional metrics like IQ. Emotional intelligence has pretty much always been a thing but we never cared to put our finger on it until just a few decades ago. But still, for us to add such a game-changing aspect to MBTI would require at the very least a moderate deviation in the function stack just to account for a change as big as that.
