That will be a mystery and no one know for sure. They can only predict and guess when that will happen but still, we don't know. Instead just wait for that happen, we should accumulate more amount of Bitcoin so we can be ready if that is happen in the near.

I will be happy if that is happen before the end of the decade and will sell my Bitcoin to take profit. Other people will do the same because they already invested from a long time ago.

Many barrier that Bitcoin need to break and that is not easy. But I am sure that will happen and that will be only a matter of time.
