The great Tom Junod reflects:
We are not going to live forever. We are not going to have our life spans scientifically amplified to biblical lengths. We will not be able to take pills that will give us the musculature of superheroes or allow us to gorge ourselves while enjoying the health benefits of starvation. We will reach our limits, and, with some hard-won variation, those limits will be they will feel like the same limits we humans have always had. We will remain human where it counts, in our helpless and inspiring relation to our own mortality.
Does this sound obvious? It shouldn't.
Indeed, what I should have said from the start is that I believe that we are all going to die, in that science increasingly believes otherwise and science increasingly has become a matter of belief. Its logic, once pointed at the eradication of disease and infection, is now inexorably pointed at aging and death, which is to say the ultimate questions that were once left to religion. ...
As it expands its realm into matters of faith, science will become more and more faith-based, and more and more energized by the off-label indication. Its promises will become harder to believe the closer they come to being fulfilled, because belief will obligate us to make choices we are not equipped to make choices once left to popes and their priests. And this is how science will finally become like religion in all things except its actuality.
