No industry holds greater potential for the application of A.I. than health care. It generates massive of amounts of data that, if properly analyzed, could have enormous implications for health costs, health outcomes and human longevity.

And yet in no industry is the gap between potential and present reality greater.

How do we close that gap? That was the conversation at a small, off-the-record lunch I moderated yesterday before the start of Fortune‘s annual Brainstorm Health event. The participants included CEOs of some well-known health care companies and top executives from Intel. Their consensus: technology is not the problem here. Data security, data privacy, siloed data, dirty data, and cultural opposition to A.I. all pose bigger obstacles. Fixing those problems in order to unlock the potential of A.I. will not be done in two or three years. It will be a decades-long project.

Still, speakers on the conference main stage were optimistic about A.I.’s ability to transform health care. “We have made a lot of progress,” said IBM’s John Kelly, and there is much more to come. Health care A.I. may turn out to be the ultimate example of Amara’s law: We tend to overstate the effects of technology in the short run and underestimate the effects in the long run.

By the way, Kelly expressed the view of many in the group that A.I. isn’t going to replace the judgment of medical professionals. “It is always going to be human plus machines making the decisions.”

Brexit Twist

British Prime Minister Theresa May has for the first time indicated willingness to cross her "red lines." With Parliament unable to find a majority for any Brexit option, she now wants to reach a compromise with Jeremy Corbyn's opposition Labour Party that could win the support of most lawmakers. This will involve asking the EU for another short extension. If the cross-party talks fail, May said she will accept whatever Parliament agrees to do. So, chances of a no-deal Brexit just went down, and those of a "soft Brexit" (with the U.K. remaining in a customs union with the EU) and a second referendum just went up. Guardian

Uber Lobbying

Uber spent $2 million lobbying for congestion charges in New York, which will be introduced in a couple years' time.

Fake News

Facebook's WhatsApp is taking a new tack in the fight against fake news in India, where elections are imminent—it's launching a helpline where users can check if the information or photos they have been sent are genuine or misleading. This isn't the first such fact-checking service to be established in India, but it is the first to be set up by WhatsApp itself. BBC

Panama Papers

The Danish tax authority is suing 34 companies from the country that were named in the Panama Papers tax avoidance scandal. It wants the taxes it was owed. Some of the companies can't pay up, so the Tax Agency is suing their management instead. It's considering suing another 50 companies, too. Reuters
