Your grandmother was from a generation where you need to use your resources available, think and solve your problems, that's why she (and a fair number of that generation forwards could) do things. (many to not say almost all products came with manuals)My grandmother born in 1916. Turned on a Performa 6400 mac os 7.5.3. She was online reading the new, printing stuff out, e-mailing. Today people younger then me, tech savvy generation, They can't do anything with out IT.
One of the problems of younger generations it's the laziness that's come of a totally plug and play, always connected, always available, and "web-browser centric no need to install everything".
Instead of searching, building knowledge, just see the need for an ongoing "disposable content", just see an Reddit (at least it's searchable) but unless with an moderator/community effort, you see the same question day after day in many subreddits. Facebook I totally give up those communities and platforms.
I'm really curious of what will least of all of it.
