What could go wrong?

Shu points out that the human body performs computations that are naturally more faster than even the fastest silicon-based computer.

“No matter how fast tomorrow’s conventional silicon-based computer can become,” their article states,” in order to solve specific classes of problems, it may take the fastest silicon-based computer months or even years to process the calculations. This is mainly due to the serial computing nature of the conventional silicon-based computer.”

So Shu and his students manipulated stands of DNA at the test-tube level.
