A fascinating article from CNBC:
Whilst the notions that MRI scans can be used to decipher thoughts as they form is far from new, tests have demonstrated the prediction of answers to an array of questions, the concept of wearable technology making everyone able to communicate telepathically is interesting. Aside to questions over side-effects and security, it once more raises questions over the means by which we could boost our own inherent abilities, rather than employing technology and a series of algorithms to enable communication.
Further, the cynic in me also thinks that this is the ultimate in lazy communication. We ceased talking and writing in favour of texting each other — pretty soon we will simply think.
