People will be constantly entertained by implanting an entertainment unit. No one will ever be "bored." Ever.
People will telecommunicate with others without the need of external devices, such as computers or telephones. No one will ever be "lonely." Ever.
People will be able to change their faces whenever they want. No one will ever be "Rick Astley." Ever.
YOU'VE BEEN RICK ROLLED!!!
