According to Strauss-Howe generational theory, culture and politics move in 80-year cycles. The 2010s are a crisis decade, like 1930s were. Also, millennials are a team-oriented, practical "civic" generation like the WW2 veterans.
Then, we can look forward to 2050 as an awakening time similar to 1970. People born in the 2020s and 30s will be a prophetic, idealistic generation like the baby boomers. They will rebel against millennial values like the boomers rebelled against the WW2 generation's values. 2010s culture values maturity, teamwork and pragmatic attitudes, but the prophets will be champions of youth, individualism and idealism.
But what will be the awakening about? What can they rebel against? The first thing that comes to my mind is over-reliance on digital gadgets and the Internet. Individuality will be praised and social media conformity will be despised. We can also see a "back to nature" movement like the hippies had. This time, they could expand their consciousness using biotechnology rather than narcotics and Hindu mystical practices. Furthermore, the prophets of 2050 will almost certainly look down on the right-wing populist movements favoured by millennials, on the sort of politics that gave the world Trump, Brexit and the current Polish government. But they will also despise authoritarian progressivism favoured by the SJWs. If this really happens, we can see a revival of an authentic liberal movement. If Western democracy survives, indignation at tyrannical governments in the Third World could bring neoconservatism back to life.
I wonder what sort of religious ideas will the awakening bring. A prophetic generation always wants some sort of spirituality, but this time it could be a space-oriented, cosmic worldview like the spirituality of Olaf Stapledon.
