Back then in 2005 I came across a Newspaper article by World's Renowned Futurist Raymond Kurzweil Titled
Singularity is Near" . The article listed the most chilling predictions made by Raymond. The one that got me the most was the prediction about human achieving Immortality by 2050 or something(not very sure) . Since then I became interested in the science of Immortality until few years ago when a shocking event forced me lose interest in humanity and i became more aligned with Spirituality.
I was going through a website and found an article titled:
Scientists Have Mathematical Proof That It's Impossible to Stop Ageing https://sciencealert.com/cancer-versus-aging-cells-eternal-youth-mathematical-impossibility I did a Google search to confirm the authenticity of the contents and found similar article on a credible site:
Sorry, You Can't Stop Aging – Here's the Math to Prove It https://www.livescience.com/60825-aging-is-inevitable-according-to-math.htmlI have my doubts though when it comes to doubting what humans can achieve... I believe nothing is impossible to humans and the word "NEVER" isn't in the dictionary of those determined to succeed.
My only doubt however is if humanity could survive another 3 decades to be able to find a cure for ageing.
Read the article more carefully. The "you can't stop aging" line is meant asymptotically. It doesn't mean that you can't lower the rate at which humans age. So with this paper it's still very well possible to reduce the rate of aging to a point where it's virtually non-existant for humans.
And that's not even taking into account exchanging body parts or even swapping into a digital existence.
So yes, it's very well possible that humans would be capable of extending their lifetime indefinitely.
But, immortality is a whole different story. You can be capable of living forever, but your body could still be destroyed if someone really wanted to do that.
