It will not happen in the next generation or two, no. I think it's a thousand years away, give or take ... and then it is still not total; there will always be people stuck in religious ideation.

We do not need to develop past it, we simply need to understand it and control our thinking.
The reason our species has been so successful is our ability to imagine, to ponder possibilities and to tell stories.
Should we ever develop to a point where we lose that, our society will stagnate and eventually collapse.
All that is require to achieve your desired effect is education and training of the young, allowing critical thought to separate out at all times the real from the imaginary.

Myth-making is much more deeply embedded in our genetic makeup than rational thought is. You do the math.

Never. The need for myth, scapegoats, and irrational comfort associated with dying, is too great.

Not in this, our, lifetime. Hell, even in Star Trek there were plenty of examples.

What is the difference between mythical and wishful thinking? We are headed over a large precipitous and refuse to see it coming. Wishful thinking, hope faith in technology or just laziness are many reasons for our blindness. To me religion is just a minor cause in the world's problems.

I don't know if I agree with the "suicidal" association. But I do believe mysticism (particularly religious mysticism) is a disease/mental illness. And no, we won't outlive it. However, we are moving in the right direction as more and more people are realizing that religions are (and have always been) a hoax and are walking away.

i do no foresee that we will ever do that.

It's not suicidal. Close to 7,000,000,000 people believe in fairy tales, and most of them believe the fairy tales tell them to keep having more kids.

It's literally an evolutionary strategy. If some humans are inclined to believe religious nonsense, and some religious nonsense tells them to have more kids, before long almost all humans will believe in the religious nonsense that tells them to have more kids.

We see the trends of less attendance at churches. However, in America specifically you have a government that allows too many of its laws to be based on religion or controlled by religion. Until that nonsense stops, religion isn’t going anywhere here. In Canada and Europe religion plays a much lesser role.

imo it is happening right now, but i would suggest "supernatural" there over mythical, as we have a diff definition of "myth" now that does not honor the definition of "mythology," which was until very recently the only way humans had to pass truth to the next generation. The Bible is a mythology, and was not meant to be read literally except by "the wise, the blind" as It repeatedly points out

It'll never happen. Mankind has proven its pathological need to believe in a realm populated by supernatural beings superior to themselves who can offer them guidance, forgive their sins, and save them from death. Tell people a lie that's reassuring enough and they'll follow like lemmings...right over a cliff.
