While it is well established that communism is inevitable, how and when is still up to debate because of some minor historical setbacks (despite most of them not being actual communism) like the fall of the Soviet Union.
In this thread let's make educated guesses about the coming of the great evening when we will seize the means of productions and eliminate the bourgeois class system.
And my guess is Elon Musk will bring communism when he puts the last nail in the coffin of global capitalism by creating fully automated driverless trucks /taxis and causes 30% of the total workforce to become unemployed. I'm not saying he will do it on purpose but eventually that will be the spark that ignites the revolution as no population except maybe the us will stand massive wealth inequality for that long with no perspective of improvement since the ruling class now own all the robots.
