That is not what I meant. I don't say those users are worse for it, rather that user interfaces of course need to accommodate such approaches. Such as placing a notice at the old location which directs users to the new location (like when a brick-and-mortar-store moves).

I have no desire for or against systemd, but I understand that this is how the world revolves and that one has get along with the times.

It is just willingness to learn. How you learn and how fast you learn is of course age dependent, but the attitude towards learning new things and breaking out of routine is what matters more.
