Oh this is question that make me cry knowing that one day i will surely leave this world.
It is your right to make technology grow most especially musing because this is a very educative and useful platform. So it will rather be advisable to tell it to young one and family, introduce it most especially let them know your password so that after you are gone they can continue the good work for generations to come.
And i surely know that even the owner of musing will take to this advise also in order to make musing go a long way for generation and generations to come.
It can also be use to tell your followers most especially the community that you are no more but the first thing you have to do is to leave a good legacy to the steemit community, they can even help your family with upvote earning or transfer to take care of themselves.
