I'm largely self educated, but found that the more educated you are, the less you can swallow some WTS teachings and mindset. That's because higher education, unlike public school education, encourages critical thinking, thinking for yourself. So, of course it's the enemy of authoritarian, micro managing religions.
I'm sure that's why they're not big on higher education, although they've had to soften that somewhat as they need professional people for some things as much as anyone. What a quandary!
At one point, I really thought WTS theology would evolve into something more rational and more "liberal"...not in the political sense, but in the sense of doctrinal flexibility. I had hoped they would eventually outgrow and discard some of their more unsupportable and radical beliefs. I'm surprised they even accepted the new "generation" teaching as it undermines the whole 1914 thing, but apparently they had no choice, as the old interpretation was just ridiculously unfeasible with the passage of time.
But, when it tightened up even more and got even more authoritarian in the 90s, I got less and less convinced. I have this feeling that in the next few decades it will go the way of the dodo...which would be a fitting symbol for the incomprehensible doctrine they've tried to impose on people for so long.
Unless they change.
But religion in general is undergoing a gradual shift, an evolution. It has to, for it has outgrown one of it's long time social functions, that of providing moral and social control. We have other things that do that now in society, such as psychology or humanistic philosophies and people finding commonality of thought and practice through things other than religious belief, such as internet forums that address a whole variety of interests.
Someone once said that psychologist are the secular "priests" of our time. We've replaced outmoded moral codes and religions with a human understanding of the human psyche that seems to be more workable than religious codes. If religion wants to survive, it will adapt and become largely counseling/charitable/social assistance oriented without the burden of unsupportable doctrines and myth. Don't get me wrong, myth is useful. But it tells me more about the person who believes it than about what they believe.
But, I think spirituality will always be part of being human, it's been around as long as there have been modern humans. The more personal and mystical experiences and expressions will remain, because they've always been so, but religion as we currently understand it will probably not be around forever. Look how much religion has changed in just the last 200 years.
