Depends on what consciousness turns out to actually be in my opinion (which is another unknown that'll no doubt be looked back on in amazement). If it's something that can be recorded in a sense then I imagine death without having first "backed up" will be seen as a tragedy! It might be the case one day that biology is simply be the first stage of the human lifecycle and just like birth, puberty etc "death" becomes a major life milestone that involves exchanging our frail bodies for something much more durable.
