Is it really possible to extend human life to 200 and 300 years?

Human has always been fond of immortality and reaching it, and searched a lot for ways and tools to become immortal, such as incantation, magic, elixir of life, and going to remote lakes or mountain peaks, thinking that the answer is there, but all attempts ended in failure, and this obsession always existed  through arts such as the vampire, immortals, werewolves, etc. believing in the existence of immortality deeply in human thought.

Today, this obsession has returned to the ground again, not from some amateur or public, but from the elite of the rich, but they are not only rich, they are geniuses and pioneers in their business, number of them, led by the Russian billionaire (Yuri Milner) and the richest man in the world (Jeff Bezos), founder of the Amazon and Blue Origin for space research, paid huge funding to a new and mysterious company called Altos Labs.

This company was established to start the largest series of researches in an amazing new technology, called (Biological Reprogramming). This is an innovative and new way to renew living cells and prolong their life in the laboratory, can let them go back to their youth and their main goal is that they use this research to restore the bodies of animals to youth, or even bring the dead cells back to life again, and this is with the aim of prolonging the average lifespan of humans

The head of the scientific council of the company is a Japanese scientist, Shinya Yamanaka, who won the Nobel Prize in Medicine in 2012, because he discovered and proved by experiment that by adding 4 specific proteins to aging cells, we can make them return to their youth again, as if they were still born, like stem cells.

Scientifically, this idea can be realized and become a reality one day, but can it actually be implemented? Will nature leave man to disturb his systems if the average lifespan is now 60 to 80, and there is a shortage of food resources and great overcrowding and with the continuous population increase and we add to it the increase in lifespan To 200 and 300 years, does that land bear all of this, as it has already been dying for a while?
