It was ought to happen someday. Well, it happened. About a year ago, Israeli Scientists created a simple chess engine called “DNA engine.” This engine is now being trained to play complicated chess combinations. However, a man-eating Tic-Tac-Toe has been made, scientists report.

The human player makes his or her moves by dropping DNA into 3 by 3 square of wells that make up the board. The device then uses a complex mixture of DNA enzymes to determine where it should place its nought or cross, and signals its move with a green glow.

“More complex computational tasks than noughts and crosses could be tackled with different arrangements of the enzymes. But the pair acknowledge that the approach will never rival silicon computers, because human action is needed to operate the gates in system and it is not reusable” says Jenny Hogan.

But, imagine just for a second what our world would be like when our DNA based PCs feed like we do. Imagine the computation power that can be extracted from these DNA PCs. All these begs the question: Aren’t we all highly advanced DNA-supercomputers? I’ll leave answering this to you.
