It's hard to tell which side is progressing faster, although it seems that the machines are turning human at a faster rate than humans are turning into machines. The convergence is not simply a one way street. Biology is seeking silicon and silicon is immitating biology.
The question troubling me at this point is, what happens if silicon reaches the singularity before biology? Would the universe become silicon? Also does this work vice versa, could the synthetic universe become biological?
