the fact that immortality will be found - Reyep
" Everyone wanted to live forever;kings, queens, wealthy people, even urchins from the streets. The Greeks and Romans accomplished immortality through their art therefore the artist of the Renaissance imitated their actions. To capture the image of a person in a painting or sculpture meant, he would be immortalized because his image would remain after their death. (bkz:Leonardo da Vinci) became obsessed with his quest for immortality. It became an unquenchable and fiery passion, which he sought to attain through his art and ended in the (bkz:Mona Lisa). "

I found this somewhere else i just wanted to share this point that immortality is not a new subject.
The capacity of our planet is certain, some very serious measures will have to be taken. For example, people will need to be sterilized. Health education systems, production systems, all of them will be very serious changes.
I leave the rest to the imagination of science fiction writers.
If we consider that technology is constantly evolving and the basic logic of living organisms has remained the same for millions of years, immortality will be found after sufficient time and budget are spent.

The developments that have taken place so far are the production of organs in 3D printers, the production of mechanical limbs, the production of various oraganic organs, inventions in gene technology. Add inventions on stem cell anti-aging technology. A budget and time that thoroughly blends the work in all these areas is something that the owner will eventually complete this task.

It may even have been found now and is still being worked on. If our cells continue to renew themselves, this will happen.
