I mostly disagree with this argument.

I will die. CGP Grey will die. You, reading this comment, will die. Everyone we've ever known will, too. Our children, our loved ones. Even our physical and digital legacies will eventually crumble and fail.

I don't like this fact, don't romanticise it - it's, to me, the central tragedy of living. But it's inevitable, sooner or later, so you'd better at least acknowledge it.

Could we delay it? Sure, we can give it a go. But as Kurtzgesagt explained in his video, death is not a single disease, nor a man in a black hood - it is decay, inside and out, micro and macro. Forgive me for a bit of personal commentary, but as a doctor we already try as best we can to give patients as many good years as possible: we give medication to keep blood pressure down; give lifestyle advice to prevent obesity and smoking; blast the body with chemotherapy to get rid of cancer. But the decay continues, and there comes a point where the tinkering no longer does any good.

The worst deaths I have seen in hospital are of those in whom death is not acknowledged as inevitable. Perhaps the patient doesn't accept it, the relatives are desperate or the doctors too over-zealous. In the end the patient might get another week or two, but they will be miserable, and are more likely to die suddenly or in an uncontrolled manner.

Why die? Because we have to - really. The attitude that Silicon Valley or whomever can come in and hack our bodies to prevent death as if it's a new idea strikes me as a bit naive.
