People have been saying this kind of thing forever. They said it about agriculture, they said it when the Luddites attacked factories, they said it about farm automation, they said it when computers were becoming popular. I'm not so sure that this time is different - despite all the insistence, I'm sure it seemed just as serious every other time before too.
It would be facile to ignore the massive and frequently bloody consequences of such previous economic disruptions. People didn't just go through a period of anxiety and then drift into new jobs and feel content again during previous industrial revolutions.
Edit: it all depends on tone... I still read the comment with the tone that implies disruptions as being as negative as they are positive, whereas I would frame disruptions are more positive. Granted, that's not to ignore the countless people who have had their lives uprooted by not being able to keep up with fast moving societies.
