It looks like the future of Europe is to be a stagnant backwater where the standard of living slowly declines. It’s likely to be overrun both by Russia and by mobs of economic migrants with Enlightenment-hostile values and cultures.
My guess is that the region will deteriorate for 200-300 years and then as those mobs aforementioned and their terrible cultures cool out, it’ll flourish once again — after some brutal wars and genocides.
Good times, good times.
