Even those that retire and may think they do not have to adapt to the new world are mistaken on their beliefs, and the reason for this is that they do not live in a bubble and they need to interact with the world, so for example those that retired a decade ago may not be as familiar with smartphones than those that are retiring just now, and this is a problem as now a great deal of what we do is done through those devices, and if they do not know how to use them and they are not willing to learn they are seriously handicapping themselves.
Precisely that is the difference between people who retired a decade ago and those who retire now because previously the use of devices such as smartphones was only needed for one or two jobs, making more people not want to use smartphones because they didn't there is a lot more work done with the device. Meanwhile, nowadays almost all work has to be done using a smartphone device if the job is in the government sector or in the civil servant category, so there is a very real difference between people who retired in the past and those who retire now.
