The Download: Google’s AI Overviews nightmare, and improving search and rescue drones

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

Why Google's AI Overviews gets things wrong

When Google announced it was rolling out its artificial intelligence-powered search feature earlier this month, the company promised that Google will do the googling for you."The new feature, called AI Overviews, provides brief, AI-generated summaries highlighting key information and links on top of search results.

Unfortunately, AI systems are inherently unreliable. And within days of AI Overviews being released in the US, users quickly shared examples of the feature suggesting that its users add glue to pizza, eat at least one small rock a day, and that former US president Andrew Johnson earned university degrees between 1947 and 2012, despite dying in 1875.

Yesterday, Liz Reid, head of Google Search, announced that the company has been making technical improvements to the system.

But why is AI Overviews returning unreliable, potentially dangerous information in the first place? And what, if anything, can be done to fix it? Read the full story.

AI-directed drones could help find lost hikers faster

If a hiker gets lost in the rugged Scottish Highlands, rescue teams sometimes send up a drone to search for clues of the individual's route. But with vast terrain to cover and limited battery life, picking the right area to search is critical.

Traditionally, expert drone pilots use a combination of intuition and statistical search theory"-a strategy with roots in World War II-era hunting of German submarines-to prioritize certain search locations over others.

Now researchers want to see if a machine-learning system could do better. Read the full story.

What's next for bird flu vaccines

In the US, bird flu has now infected cows in nine states, millions of chickens, and-as of last week-a second dairy worker. There's no indication that the virus has acquired the mutations it would need to jump between humans, but the possibility of another pandemic has health officials on high alert. Last week, they said they are working to get 4.8 million doses of H5N1 bird flu vaccine packaged into vials as a precautionary measure.

The good news is that we're far more prepared for a bird flu outbreak than we were for covid. We know so much more about influenza than we did about coronaviruses. And we already have hundreds of thousands of doses of a bird flu vaccine sitting in the nation's stockpile.

The bad news is we would need more than 600 million doses to cover everyone in the US, at two shots per person. And the process we typically use to produce flu vaccines takes months and relies on massive quantities of chicken eggs-one of the birds that's susceptible to avian flu. Read about why we still use a cumbersome, 80-year-old vaccine production process to make flu vaccines-and how we can speed it up.

The big story

How to fix the internet

October 2023

We're in a very strange moment for the internet. We all know it's broken. But there's a sense that things are about to change. The stranglehold that the big social platforms have had on us for the last decade is weakening.

There's a sort of common wisdom that the internet is irredeemably bad. That social platforms, hungry to profit off your data, opened a Pandora's box that cannot be closed.

But the internet has also provided a haven for marginalized groups and a place for support. It offers information at times of crisis. It can connect you with long-lost friends. It can make you laugh.

The internet is worth fighting for because despite all the misery, there's still so much good to be found there. And yet, fixing online discourse is the definition of a hard problem. But don't worry. I have an idea. Read the full story.
