Latest from MIT Tech Review – The Download: Chatbots could one day replace search engines. Here’s why that’s a terrible idea.

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

Chatbots could one day replace search engines. Here’s why that’s a terrible idea.

Large AI models can simulate natural language with remarkable realism. Trained on hundreds of books and much of the internet, they absorb vast amounts of information.

There’s growing excitement in the tech sector that they might one day replace search engines. In theory we could simply ask a computer a question and it could return a bite-size answer. The trouble is, language models are mindless mimics. They do not understand what they are saying, and cannot reason about what their words convey.

Some researchers are concerned that chatbot search engines could worsen our existing lack of critical thinking around search results. A natural language answer can hide complexity behind a veneer of authority that is not deserved. Experts also fear that it could lead to more misinformation and more polarized debate.

Why using the oceans to suck up CO2 might not be as easy as hoped

The world’s oceans are amazing carbon sponges, capturing a quarter of human-produced carbon dioxide when surface waters react with the greenhouse gas in the air or marine organisms gobble it up as they grow.

Some research groups and start-ups want to help accelerate this natural process by adding certain minerals to the oceans that could help them lock up even more carbon and slow climate change. The idea has attracted a lot of excitement and investment.

However, a number of recent studies suggest that some of these approaches may not be as effective as scientists had hoped.

That’s disappointing news, because the world may need to suck up an additional 10 billion tons of carbon annually by midcentury to limit warming to 2 ˚C, according to a recent report. Read the full story.
