求翻译：而且，我们知道机器人无法和人类完全一样，但是取代人类就一定要完全一样吗？可能性在于它有多大的可实行性，不在于有多大的相似度。人类取代恐龙成为地球的主宰者，并不是因为人和恐龙相像。是什么意思？

Moreover, we know that the robot can not be exactly the same and human, but to replace the human must be exactly the same? Possibility is that it is how viable is not that much similarity. Human replace the dinosaurs to become the master of the Earth, not because of human and dinosaur similar.
