Your first point doesn't make sense to me. Human knowledge is not encoded in DNA in a single lifetime and more abstract concepts will never be "passed" down to offspring. This is where artifical lifeforms have a huge advantage. Their offspring can directly recieve knowledge from their parents. We can also do tons of other things that would be unrealistic, such a 1-parent cloning, n-parent children where n > 2, children with no parents, etc. Just because we design systems that vaguely model real life in evolutionary computing doesn't mean we are constrained by the same laws of genetics. FWIW, I agree that any form of intelligent machines that surpass humans at general aptitude tests are decades away. We may not even see them in my lifetime and I'm only 22 years old.
