Artificial intelligence holds huge promise in health care. But it also faces massive barriers
Better diagnoses. Personalised support for patients. Faster drug discovery. Greater efficiency. Artificial intelligence (ai) is generating excitement and hyperbole everywhere, but in the field of health care it has the potential to be transformational. In Europe analysts predict that deploying ai could save hundreds of thousands of lives each year; in America, they say, it could also save money, shaving $200bn-360bn from overall annual medical spending, now $4.5trn a year (or 17% of gdp). From smart stethoscopes and robot surgeons to the analysis of large data sets or the ability to chat to a medical ai with a human face, opportunities abound.

Ukraine must prepare
Melting ice sheets do more than raise sea levels
America should help it find a better strategy
There is still a narrow path out of the hellscape of Gaza. A temporary ceasefire and hostage release could cause a change of Israel’s government; the rump of Hamas fighters in south Gaza could be contained or fade away; and from the rubble, talks on a two-state solution could begin, underwritten by America and its Gulf allies. It is just as likely, however, that ceasefire talks will fail. That could leave Israel locked in the bleakest trajectory of its 75-year existence, featuring endless occupation, hard-right politics and isolation. Today many Israelis are in denial about this, but a political reckoning will come eventually. It will determine not only the fate of Palestinians, but also whether Israel thrives in the next 75 years.
It is becoming harder for investors to ignore politics
Investors differ in their approach to elections. Some see politics as an edge to exploit; others as noise to block out. Even for those without a financial interest, markets offer a brutally frank perspective on the economic stakes. As elections approach in America and Britain, as well as plenty of other countries, that is especially valuable.
