We will all die, and this time will pass - this is completely inevitable. There is no way to not vanish, the closest you can come is being remembered.

Our civilization may well continue and prosper for a thousand years more, but unless we care about being remembered, they will have no idea what Pink Floyd, or Harry Potter, or A Hundred Years of Solitude, or an iPhone, or Linux, or anything else you consider important of our time were/was. Just like we have almost no idea about the pop culture or songs of people living in, say, the area of Berlin in the year 1022 was.
