Guys you're missing the fact that we would be able to know so much about each other!
There would be no such thing as miscommunication, if you had an idea you wouldn't have to explain it words you could just think it, if you were trying to explain something to someone you could just think it to them. You could contact anyone on any side of the planet at will. You could learn so fast by just having being able to directly connect to information. You could be almost omniscient with the potential of all the human knowledge ever made in existence inside your head.
Obviously this wouldn't all be inside your head at the same time, it would be similar to the internet. You would only connect to one person at a time, each connection would need to be authorized by both the sender and receiver just like a computer connecting to a website. Identity theft is ALREADY an issue, every time you post your credit card number online, or even not online and use it for a store, there is a chance someone could steal it. So if you're that scared of identity theft, don't go online or store any personal information on an electronic device.
The internet has done so much for humanity, what if we could have an even better internet that's works directly from our minds. Anytime, anyplace, more information than ever before.
