Microsoft's Bill Gates - Artificial Intelligence is a threat to humanity

Humans should be worried about the threat posed by artificial Intelligence, Bill Gates has said.

The Microsoft founder said he didn't understand people who were not troubled by the possibility that AI could grow too strong for people to control.
Artificial Intelligence (AI) is a field that has a long history but is still constantly and actively growing and changing. In this course, you’ll learn the basics of modern AI as well as some of the representative applications of AI. Along the way, we also hope to excite you about the numerous applications and huge possibilities in the field of AI, which continues to expand human capability beyond our imagination.

Bill Gates said he could not understand why people were not concerned by AI

Mr Gates contradicted one of Microsoft Research's chiefs, Eric Horvitz, who has said he "fundamentally" did not see AI as a threat.
Mr Horvitz has said about a quarter of his team's resources are focused on AI.
During an "ask me anything" question and answer session on Reddit, Mr Gates wrote: "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well.
"A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don't understand why some people are not concerned."

His view was backed up by the likes of Mr Musk and Professor Stephen Hawking, who have both warned about the possibility that AI could evolve to the point that it was beyond human control. Prof Hawking said he felt that machines with AI could "spell the end of the human race".
Mr Horvitz has said: "There have been concerns about the long-term prospect that we lose control of certain kinds of intelligences. I fundamentally don't think that's going to happen."
He was giving an interview marking his acceptance of the AAAI Feigenbaum Prize for "outstanding advances" in AI research.

"I think that we will be very proactive in terms of how we field AI systems, and that in the end we'll be able to get incredible benefits from machine intelligence in all realms of life, from science to education to economics to daily life."
Mr Horvitz runs Microsoft Research's lab at the parent company's Redmond headquarters. His division's work has already helped introduce Cortana, Microsoft's virtual assistant.
Despite his own reservations, Mr Gates wrote on Reddit that, had Microsoft not worked out, he would probably be a researcher on AI.
"When I started Microsoft I was worried I would miss the chance to do basic work in that field," he said.

He added that he believed the firm he founded would see "more progress... than ever" over the next three decades.
"Even in the next 10 [years,] problems like vision and speech understanding and translation will be very good."
He predicted that, in that time, robots would perform tasks such as picking fruit or moving hospital patients. "Once computers/robots get to a level of capability where seeing and moving is easy for them then they will be used very extensively."
He said he was working on a project with Microsoft called "Personal Agent", which he said would "remember everything and help you go back and find things and help you pick what things to pay attention to".
He wrote: "The idea that you have to find applications and pick them and they each are trying to tell you what is new is just not the efficient model - the agent will help solve this. It will work across all your devices."

But he admitted that he felt "pretty stupid" because he cannot speak any language other than English.
"I took Latin and Greek in High School and got As and I guess it helps my vocabulary but I wish I knew French or Arabic or Chinese.
"I keep hoping to get time to study one of these - probably French because it is the easiest... Mark Zuckerberg amazingly learned Mandarin and did a Q&A with Chinese students - incredible," he wrote.

AI research is highly technical and specialized, and is deeply divided into subfields that often fail to communicate with each other. Some of the division is due to social and cultural factors: subfields have grown up around particular institutions and the work of individual researchers. AI research is also divided by several technical issues. Some subfields focus on the solution of specific problems. Others focus on one of several possible approaches or on the use of a particular tool or towards the accomplishment of particular applications.
The central problems (or goals) of AI research include reasoning, knowledge, planning, learning, natural language processing (communication), perception and the ability to move and manipulate objects. General intelligence is still among the field's long term goals. Currently popular approaches include statistical methods, computational intelligence and traditional symbolic AI. There are a large number of tools used in AI, including versions of search and mathematical optimization, logic, methods based on probability and economics, and many others. The AI field is interdisciplinary, in which a number of sciences and professions converge, including computer science, mathematics, psychology, linguistics, philosophy and neuroscience, as well as other specialized fields such as artificial psychology.
The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—"can be so precisely described that a machine can be made to simulate it."This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings endowed with human-like intelligence, issues which have been addressed by myth, fiction and philosophy since antiquity. Artificial intelligence has been the subject of tremendous optimism but has also suffered stunning setbacks. Today it has become an essential part of the technology industry, providing the heavy lifting for many of the most challenging problems in computer science^.
