Please forgive me if I have misunderstood you.
I am not sure what relevance ‘pop-science’ has unless pop science means non science.
I get that you are saying ‘maybe, possibly, not completely ridiculous to think’, etc., however until it has been demonstrated to be a possibility, the idea that a human might live until 150 is just about as preposterous as the articles’ postulation of the potential for physical immortality.
Something which is evidenced to be not possible does not suddenly become ‘possible’ just because one can imagine it.
That’s a long and boring response.
The evidence that no one can live past 123 is that no one has ever lived past 123. We have a sample size of billions on that statistic.
Some low quality science journal says that ‘maybe we could live forever, or like, 150 or something’ and I say ‘cool story bro’.
I can imagine that it might be true, but that does not make it possible.
Extraordinary claims require extraordinary evidence.
People like you are why Iemmy is almost as bad as Reddit… talking in circles, saying nothing.
