Author has written this passege becuse simlple thing - life is very dificult in it core.
Not everything in our life we can call living.
Even if scientists can create digital anlgoritm, which can to live and to die, to mutate and to reproduce, not averyone can say that it's alive.
Novadays people dont have any clear definition of life, because nobody dont know wat is it is.
What do you think this?
