Before you get too excited about those artificial intelligence doctors we’ll all have someday, you should read this briefing note from the Nuffield Council on Bioethics, a London-based group that ponders the tough ethical questions about medicine.

What they're saying: The Council has a pretty handy guide to the things that can go wrong with AI. For example, it’s not always reliable. (In one clinical trial, an app incorrectly told doctors to send home patients with asthma.)

  • It can’t always explain its decisions, as Axios’ Ina Fried wrote about here.
  • It can be biased, if there are biases in the data used to train them.
  • Patients could get isolated if they’re dealing with AI all the time instead of people.
  • It will have to be super strict about data privacy and security.
  • It could be used for bad things, like surveillance.

The bottom line: It’s clearly meant to be a glass-half-empty look at AI, but the point is that we should all think it through a bit and not just embrace AI because it’s cool.

It's harder to fill the Cabinet

It's harder now for presidents to win Senate confirmation for their Cabinet picks, an Axios data analysis of votes for and against nominees found.

Why it matters: It's not just Neera Tanden. The trend is a product of growing polarization, rougher political discourse and slimming Senate majorities, experts say. It means some of the nation's most vital federal agencies go without a leader and the legislative authority that comes with one.

Exclusive: Hundreds of kids held in Border Patrol stations

More than 700 children who crossed from Mexico into the United States without their parents were in Border Patrol custody as of Sunday, according to an internal Customs and Border Protection document obtained by Axios.

Why it matters: The current backup is yet another sign of a brewing crisis for President Biden — and a worsening dilemma for these vulnerable children. Biden is finding it's easier to talk about preventing warehousing kids at the southern border than solving the problem.

Pompeo plots 2024 power play

Mike Pompeo has quickly reentered the political fray, raising money for Republicans, addressing key political gatherings and joining an advocacy group run by Donald Trump's former lawyer.

Why it matters: The former secretary of state is widely considered a potential 2024 presidential contender. His professional moves this week indicate he's working to keep his name in the headlines and bolster a political brand built largely on foreign policies easily contrasted with the Biden White House.
