Do you think that we'll see progress towards a socialist world in the next 60 years? And why?

yes.
it won't come from any existing socialist state tho, it will come from the contradictions that are emerging in the global order.

i say this because there has been only one time in which an existing socialist state brought about socialism in another country and it was WWII. the rest have been internal.

here are some videos you can watch which take a materialist analysis of the current situation in the context of past wars and revolutions.
