Perhaps there is a future where we get a general DNA mod early in our lifecycle that primes us for easier regeneration later in life.

  Assuming that at some point in the next 100 years we are able to develop an artificial womb, so women won't have to damage their bodies by giving birth, not only will birth become easier for everyone but it will also be easier to do such modifications with the fertilized egg.

    This is artificial womb idea is evolutionary suicide. Human reproduction would eventually cease to function without artificial wombs as selective pressure for natural reproductive fitness disappears, causing genetic drift to go unrestrained. Should humanity ever go through a technological bottleneck (solar flare?) where artificial wombs are no longer available, then the population would decline rapidly as only those who can still reproduce naturally will be able to have offspring. The subsequent bottleneck in human capital will ensure that it will take ages for humanity to reach the same level of technological ability, if we ever will.

      "Human reproduction would eventually cease to function without artificial wombs as selective pressure for natural reproductive fitness disappears" I don't mean to be rude. I'm guessing English is not your first language?

        This sentence is entirely clear within the context of genetic evolution.

          You are assuming that they meant to write “with” when they accidentally wrote “without”? Artificial wombs don’t currently exist, so the sentence has no meaning as written. But even if we re-write the sentence so it obeys the normal rules of English grammar, it is still deeply silly — the whole point of artificial wombs is that we would then be free of many of the problems that now plague human reproduction, such as infertility.

      There were times in the past where the human population was reduced to only tens of thousands people [0]. In 10,000 BC population was estimated to be in a range roughly between 1 and 10 million individuals.

      Natural selection also means death. We already go to extraordinary measures to allow people who could not otherwise produce or bear children to do so. A very large number of women who would otherwise die in childbirth, possibly with the death of the child, now survive. "Natural selection" would kill them. To hell with natural selection.
