You know the saying that everyone will get their 15 minutes of fame. It makes total sense since each generation has its "40 years of fame" - their potent and active years. However the next cycle could be much more potent since current situation is a bit different. The boomers are basically still in power and refuse to give it up, they have been "famous" for the past 60 years, effectively stealing 20+ years of "fame" from the next generation. Once this gerontocracy ends, this will cause all of the "potential energy" for change that has been suppressed to be released pretty quickly and the world will change drastically. We will basically skip one generation during the power transfer and the young generation will probably be in power for more than 40 years as well. It will be something like the current situation in the British monarchy - the queen lived for so long, she basically left just a few years to her son to be in power and he will soon be replaced with her grandchild who will probably reign for longer than usual and probably make a bigger impact.
