It would be very difficult to teach the elders about bitcoin if they also did not understand today's technology such as computers and smartphones.
surely they will still choose the traditional way that they have understood for a long time.
Totally true, if they do not have fundamental knowledge about the modern technology then you better start with that one because it will interconnect along the way. In my opinion, educating elderly about bitcoin and modern technology in general is a pretty good thing because most them will be leaving inheritance and there will entitled pieces of shit family member that will try to trick the inheritance, if we encouraged the education of elderly with modern technology then more entitled POS family member will not be able to trick them.
