Speculation on immortality

Achieving immortality (in the strict physical sense of not dying at all) may be just a matter of waiting to be born after a certain period in time. I proceed to try to convincing you of that. Consider these facts:

• life expectancy has been increasing throughout history - from 30-40 years during the Paleolithic/Neolithic, 40-50 in the Middle Ages, to 70-80 currently (early 21st century);
• increase of life expectancy is correlated with development and technology advances;
• technology is evolving faster and faster nowadays.

It is not far fetched to make the prediction that there may come a period in history when those people born after that time will have a life expectancy such that, when the time arrives for them to die as expected, technology will have evolved to a point where life expectancy will have increased a few more years. Then, after living those extra years, technology will again have evolved a little further to increase life expectancy a little further. Then, after living those extra years, technology will again have evolved a little further to increase life expectancy a little further. Then, after living those extra years, technology will again have evolved a little further to increase life expectancy a little further.
You get the picture. Life goes on and on and on, with life expectancy increasing unboundedly.
Ergo, immortality has been achieved. It is an idea which borrows quite obviously from the Zeno's paradox of Achilles and the tortoise, with Achilles corresponding to Death and the tortoise being what we may call the Technology-Driven Life Expectancy Extension.

Now comes the speculative part: from extensive and complex calculations I have made, I can say that the date of 8th July 2037 at 01:24h AM (GMT) may be the point at which people born after that date will on average be immortal, while those born earlier will have to die sooner or later. So, if you are reading this and plan to have children around that date, that's one aspect to consider in your planning.
