World-renowned scientist and author Stephen Hawking had much to say on the future of tech in an interview with the BBC on Tuesday. 

Hawking, whose motor neuron disease, ALS, was diagnosed in 1963 when he was 21, took a fair, calculated look at the pros and cons of technological progress. After all, he's an expert: Hawking was one of the first people to become connected to the internet. 

While he sees many benefits to artificial intelligence--notably, the Intel-developed computer system ACAT that allows him to communicate more effectively than ever--he echoes entrepreneurial icons like Elon Musk by warning that the completion of A.I.'s potential would also "spell the end of the human race."

Note that Hawking's reservations haven't stymied his own ventures: As recently as September, Intel and Hawking announced that they're working together to develop an internet-connected wheelchair. 

Here are three notable quotes from the interview: 

1. "[My voice] has become my trademark, and I wouldn't trade it for a more natural voice with a British accent. I am told that children who need a computer voice want one like mine." 

Hawking has a speech synthesizer that sounds robotic, as it was originally designed for a telephone directory service. His unwillingness to sacrifice what makes him unique also rings true for the best entrepreneurs, who defy characterization and can hold their own. 

2. "The internet has speeded up communication research, but at the high price of invasion of privacy." 

While Hawking credits the Web for the convenience it brings to human life, he also nods to its dangers. He specifically named pornography and cyber threats. 

3. "I think the development of full artificial intelligence could spell the end of the human race. Once humans develop artificial intelligence, it will take off on its own and design itself at an ever-increasing rate."

He's not the only one to think so: Recall Elon Musk's recent assertion that A.I. is our "biggest existential threat."
