We all know that people have become addicted to their smart phones — and now Silicon Valley insiders say this is exactly what the tech giants wanted. Founding Facebook president Sean Parker told Mike Allen yesterday that he has become "something of a conscientious objector" to social media, joining the small group of insider voices exposing and criticizing Silicon Valley's operations.

The big picture: The shiny newness and mystery of Silicon Valley is wearing off. Inner operations of the most powerful tech giants are being exposed — Facebook pitches partisan data to help election advertisers, foreign actors can easily manipulate Twitter, and now developers have always intentionally designed apps to keep our brains addicted. The insiders who are speaking up are turning on the tech world they helped create — as if they're trying to clear their guilty consciences.

  • Here's what Parker said: "The thought process that went into building these applications, Facebook being the first of them, ... was all about: 'How do we consume as much of your time and conscious attention as possible?'" He explained that Facebook's "likes" and "comments" notifications are dopamine hits, keeping addiction alive, "It's a social-validation feedback loop ... exactly the kind of thing that a hacker like myself would come up with, because you're exploiting a vulnerability in human psychology."
  • Tristan Harris, a former product philosopher at Google who has worked at Apple, Wikia and Microsoft, has spoken out about how our minds have been "hijacked" by our phones.On 60 Minutes earlier this year, he held up his smart phone, saying, "This thing is a slot machine... every time I check my phone, I"m playing the slot machine to see, 'What did I get?' This is one way to highjack people's minds, to form a habit."
  • He added that "there's a whole playbook of techniques that get used to get you using the product for as long as possible."
  • Justin Rosenstein, who created the Facebook "like" button and helped develop GChat, has self-imposed limits to his access of smart phone apps because of their addictive properties.He told the Guardian: "It is very common for humans to develop things with the best of intentions and for them to have unintended, negative consequences."
  • Biz Stone, who co-founded Twitter and recently returned to work for the company, has expressed some of his own regrets about how Twitter was built. He told Inc.: "We made a mistake when we added the Mentions tab. All of a sudden, you could see anyone who was mentioning you on the site. We put the onus on users to block someone."

Don't forget: These advocates for change in Silicon Valley once worked to create this environment, and many still profit from it. And that point isn't lost on the critics.

  • Ben Thompson, who writes the tech blog Stratechery and has worked for Apple, Microsoft and Automattic, tweeted: "Silicon Valley critics eating up Sean Parker's comments about Facebook because it fits their pre-existing views is certainly fascinating to watch." He has since deleted the tweet.
  • Hunter Walk, a former prominent Google/YouTube employee, replied to Thompson: “[W]aiting for one of our luminaries who comes to this realization to then also decide their fortune is dirty & donate all their money to social causes."

Reality check: Despite all of their issues, these companies are reporting record users and profits. And polls, including a SurveyMonkey poll for Axios, have found that they retain broad support nationwide.

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."
