"Yes, biology is complicated, but it's actually simpler than most other technologies we are dealing with. The reason is that we have received a great gift that biology has given to us. We can just take a little bit of DNA and stick it into a human stem cell, and all the rest of it is self-assembled. It just happens. It's as if a master engineer parked a spacecraft in our back yard with not so many manuals, but lots of goodies in it that are kind of self-explanatory. You pick up something and you pretty much know what it does after a little study."
Complicated in design, yet simple to use. A hallmark of great design.
Just like a master engineer from outer space…lol!
