Ouroboros
Coincidentia oppositorum
There's several flaws with the comparison.It happened naturally because the designer planned for it to be so,similar to what we do with temperature and voltage control by the regulators.
The biggest flaw is that an integrated circuit is highly optimized as a design for its purpose.
In a human body, over 90% of the DNA is non-coding. It's not used. It's not completely "junk", but it's not coding any proteins.
Our body (and the same goes for animals) contain a huge amount of unnecessary or poor designed parts.
