It appears Tesla Motors CEO Elon Musk isn't the only high-tech big-shot worried about artificial intelligence, as Microsoft founder Bill Gates has also expressed concern over what the future holds for the technology.

The 59-ear-old philanthropist revealed his thoughts on A.I.s in a Reddit Ask Me Anything (AMA) session on Wednesday, where he said humans need to be careful about developing robots so that we can avoid the kind of future shown in the "Terminator" and "Matrix" movies, according to Forbes.

"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," Gates wrote. "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."

Gates's comments follow three months after Musk called A.I.s humanity's "biggest existential threat" at the MIT Aeronautics and Astronautics' Centennial Symposium, Business Insider reported. Theoretical physicist Stephen Hawking is also worried about the technology, having written that robots have the potential to eventually "outsmart human markets" and "out-invent human researchers."

Others who have expressed their views on machines ruling the world include Google CEO Larry Page, who doesn't appear to be as afraid as others

When The Financial Times asked Page about the chances of computers taking over more jobs in the future as they evolve, he responded with "You can't wish these things away from happening," adding, however, that this could benefit our economy.

Physicist and entrepreneur Louis Del Monte said that a lack of rules for the amount of intelligence a machine is allowed to have could give machines the chance to eventually replace humans as Earth's most dominant species, Business Insider reported. Microsoft Research's chief Eric Horvitz, on the other hand, isn't as worried, saying that he believes A.I.s could eventually achieve consciousness, but it won't put humans in danger.

Gates and Musk remain committed to making sure A.I.s develop to help humanity, with Musk putting down $10 million of his own money earlier this month to fund such an effort, Forbes reported. The two geniuses also want to make sure lawmakers and public opinion don't get in the way, of using the technology, as robots have the potential to help out with future projects involving Microsoft, Tesla and SpaceX.
