every human got a psychological mechanism
the moment he witness another human talent
something in his brains gets triggered
then it appears to me later that there is some kind of talents map in each human
this map is filled with so many obstacles
the moment u over come these obstacles u reach a new talent or a development of ur current talent
but some people instead of overcoming an obstacles they copy a whole talent space and replace the obstacles with it
so a human talents is expandable
