This article was written in 2014 and I just ran across it. It is now 2018, and in the four years in between it has been pretty amazing the advances that have been made in that small span of time. Many people use wireless earbuds that have real high fidelity capability and contain microphones that can pick up voices. Natural Language Processing (NLP) has really come a long way. My company is deep into the technology and is using it to create ChatBots that will potentially replace humans in call center environments. As far as an artificial intelligence that can actually form relationships with humans, we’re still not there yet, but I’m almost certain that by 2025 or so, it’ll happen.
