The engineering of flight is something that&#x27;s achievable through simple understanding of physics laws and principles. Birds did not engineer flight, we did, and we were only able to engineer a crude version of it. The natural abilities of flight in birds are still superior in many ways to engineered flight. So, how can we assume from this that we&#x27;ll be able to build a version of ourselves that&#x27;s completely more intelligent?<p>Humans engineering functional variants of inferior species&#x27; physical capabilities is undeniably incomparable to humans engineering a better, more intelligent version of ourselves.  Maybe, a beneficial albeit simpler version can be engineered, but one that makes us obsolete? It&#x27;s hard for me to conclude that&#x27;s not a huge leap in assumption.
