People who enjoy a lot of respect — like Stephen Hawking and Elon Musk — warn of a coming artificial intelligence apocalypse. Others say the conversation has become alarmist — either that general AI is unlikely, or that even if it arrives, it will be here to help, not harm us.

Those are good debating points. But whatever the case, shouldn't we start preparing for any eventuality, especially since some researchers appear to be rushing far ahead of our think-tankers and policymakers?

91% of likely voters nationally say they are "extremely motivated to vote," including 92% in battleground states Arizona, Florida, Michigan, North Carolina, Pennsylvania and Wisconsin, according to a Change Research/CNBC Poll.

Voters last week cast ballots at nearly five times the rate they did at this point in the 2016 election, per the U.S. Elections Project. Over 39 million ballots have been cast in early voting states as of Wednesday.

Why it matters: "The settlement is the highest-profile display yet of the federal government seeking to hold a major drugmaker responsible for an opioid addiction and overdose crisis linked to more than 470,000 deaths in the country since 2000," AP notes.
