We just bought a house here last month, and we're still 'getting to know' our neighbors. [=we're still meeting our neighbors; we're still becoming acquainted with our neighbors]
It's impossible to 'know' what will happen next. = There's 'no way of knowing' what will happen next. = There's 'no knowing' what will happen next.
This is the end of the organization 'as we know it'. [=the organization has changed and will never again be the same as it was]
