Future tech is, for the most part, useful and innovative. However, a patent for some futuristic handcuffs seems more scary than fun, although it is still pretty innovative.
They look like the handcuffs we have today, but with two marked differences.
I can understand rappers and other moguls want to diversify so they can get more money or whatever they are calling it in new rap videos today. I would think that you wouldn’t want to be associated with jail or prison if you were famous, but for a rapper it seems you have to go to jail or prison to be cool.
