Maybe no new religions will pop up (soon anyways). But if old ones don't die the mess that has been created through the indoctrination brought about by these ideologies will continue unabated. I have hope in crypto though. If you can cut off the money supply into the coffers of these religion keepers you might stand a chance to starve them and bring about change. It will not happen easily though. Old ideologies don't die easily.
The secret imo is not to replace old ideologies with new ones but to render the whole fucking system useless by making it obsolete. Easier said than done, that's for sure. But I have hope. The time of crypto has come and with it promise - beyond the control of these systems of indoctrination (of the masses).
Such a thing as this absolutely cannot happen. Why not? Because people are religion-minded creatures. If they weren't, religion would have been gone long ago.
However, if it did happen, God wouldn't have any reason to hold people dear to Himself any longer. He would come and put an end to them and this universe. And maybe that's exactly why the end WILL come. It might be that there will be so few believers in Him at some time in the near future, that He will have no desire to continue this earth and universe.
Snap your fingers. Blink your eyes. God is so powerful that destroying this universe is as easy as that for Him.
