It takes the author to the end of the piece to admit that no, in fact, they did not build a computer using swarms of crabs. Right after he admits it's false he, he asserts it is true again...really...link baity bad writing for an MIT blog.<p><i>"To be fair, the results were mixed. While Gunji and co found they could build a decent OR gate using soldier crabs, their AND-gate was much less reliable.<p>However, it's early days and they say it may be possible to produce better results by making conditions inside the computer more crab-friendly. (No crabs were harmed in the making of their computer, say Gunji and co.)<p>So there you have it--a computer in which the information carriers are swarming balls of soldier crabs."</i>
