Artificial intelligence is so limited, yet such a lucrative buzzword, that companies are selling the work of hundreds of thousands of people as AI, writes the WSJ's Christopher Mims.

Why it matters: Humans have long feared AI as a jobs killer but AI's reliance on human brainpower suggests that new technology could be a boom, not a bust, for jobs.

The numbers:

  • While AI can automatically act on 83% of inappropriate content on YouTube, the remaining 17% needs human eyes, Mims writes.
  • Facebook recently announced it will double its content moderation team to 20,000 employees.
  • But the largest workforce of humans working in conjunction in AI is in China — where the government alone employs 100,000 censors.
  • If Facebook operated in China, it would need 20,000 moderators to review video content alone, a Chinese internet executive told the Journal.

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.

Trump says he doesn't know who Proud Boys are after telling them to "stand by"

President Trump told reporters on Wednesday that he doesn't know who the Proud Boys are, after saying at the presidential debate last night that the far-right group should "stand back and stand by" in response to a question asking him to condemn white supremacists.

Why it matters: The comments set off outrage and calls for clarification from a number of Republican senators. After being asked several times on Wednesday whether he will condemn white supremacy, Trump responded, "I have always denounced any form — any form of any of that, you have to denounce. But I also — Joe Biden has to say something about antifa."
