To download, or not to download:
that is the question! Whether 'tis smarter to obtain physical copy of the things you want to keep or trust to the infinite storage of clouds, with fearing they might end them.
Well I got some bad news for ya, friends; your physical media can disappear too. This has always been the case; it's why archaeologists dig up fragments of past civilisations.
We seek to keep that which we enjoy. It's perfectly understandable. So the weighing of the question is a matter of "which is more likely to survive?" Have we not all had files go corrupt on our computers? Have we not all seen favourite sites vanish from the web? Thus we backup files to the Internet, and thus we download copies to our own drives. Redundancy is the best strategy we have for permanence.
The underlying problem is not so much that either or both storage methods may fail, but the basic human reluctance to accept loss. Look at any society throughout history; they all thought they'd last forever, both collectively and as individuals. We hate the thought of dying and so concoct elaborate rituals and schemes to thwart the inevitability of our demise: pyramids or gravestones, it's all the same. "My name is Ozymandias, King of Kings!"
I have a particularly personal affinity with loss: my house burned down two years ago, taking with it every scrap of life's memorabilia from the very first toy car I ever owned to the then latest example of my creative efforts. I know loss, and I still find it hard to accept.
But many things have no 'backup' of any kind, so we must enjoy them while they still are with us - and understand that will not be forever. Not for anything.
