Zoomers and cultural revolution

In September 2016 I wrote: 

'People aged over 40 can save the planet if they act quickly, before the progressive young take over. Then all is doomed. Brexit is a start.'

Now the outlook looks much gloomier, to judge by this description of the generation that is starting at British universities now by Matt Goodwin, who predicts another cultural revolution.

Actually it is a further development of the same one which began in the 1960s. It began with American communists agitating over segregation and continued onward. Many of its leading figures were Marxist, but it is not classically Marxist.
