Do you think things would generally keep getting better for the next fifty years or are we headed for an apocalypse soon?

It will get better and it wouldn't take 50 years.

More like there will be new peace. New future until close to 30 years to go before Lucifer's Son makes his appearance.

Many will glorify him because He's so special. So loving and have awesome super natural Powers that would make the man of flesh would worship him.
