This isn't artificial intelligence, it's a robot powered by compressed gas, that has a program to tell it how to read the sides of a Rubik's cube, and another program telling it how to unscramble said Rubik's cube. Artificial intelligence is a long, long ways off, simply because computers can still only do what we tell them to, they can't learn how to do things on their own.
I would be much more afraid of your family anyway. It would be alot easier to simply kidnap a human and brainwash them to do evil. Much, much simpler. If they got to your mother, the next time she walks up behind you, she could have a butcher knife ready to drive into your back. You wouldn't suspect a thing until you had a stainless steel knife point protruding from your chest. Evil robots are really the least of your concerns.
Your argument is flawed anyway. It's like saying computers are bad because people can use them to steal from other people, or cars are bad because people can use them to run people down.
that was rigged the kid was being 2 careful while mixing it up and he ddnt mix it up enough for it to be difficult to solve
He could have sat there twisting it all day for all it would matter. There is no easy or hard for a program the unscrambles Rubik's cubes. It simply does as it is programed, and at the end of the loops and if else statements, you get a solved Rubik's cube.
