Moving on to new technologies just puts more people out of work with nothing to replace their old jobs.
Additionally, technology is neutral regarding human nature. As we grow older, we are less comfortable with shifting around and there are attachments that make it more difficult.
Sure, it's great to be rootless and fancy-free when you're in your 20s, but when you hit 40 or 50, you have to start thinking about how it's all going to end.
Technology is not about putting a few people out of "work", but about freeing people from it altogether.
The idea that we no longer need as much labor to sustain ourselves is nothing new. But it appears that we're completely willing to convert the surplus into improvements in quality of living. What we at one point might consider a creature comfort, we gradually elevate to the level of necessity. Cars, air conditioning, 2 day weekends. You name it.

The End of Work: The Decline of the Global Labor Force and the Dawn of the Post-Market Era is a non-fiction book by American economist Jeremy Rifkin, published in 1995 by Putnam Publishing Group.[1]
In 1995, Rifkin contended that worldwide unemployment would increase as information technology eliminates tens of millions of jobs in the manufacturing, agricultural and service sectors. He traced the devastating impact of automation on blue-collar, retail and wholesale employees. While a small elite of corporate managers and knowledge workers reap the benefits of the high-tech world economy, the American middle class continues to shrink and the workplace becomes ever more stressful.
As the market economy and public sector decline, Rifkin predicted the growth of a third sector—voluntary and community-based service organizations—that will create new jobs with government support to rebuild decaying neighborhoods and provide social services. To finance this enterprise, he advocated scaling down the military budget, enacting a value added tax on nonessential goods and services and redirecting federal and state funds to provide a "social wage" in lieu of welfare payments to third-sector workers.[1]
