Brain computer interfaces (BCIs) are electrodes put in paralyzed people's brains so they can use imagined movements to send commands from their neurons through a wire, or via radio, to a computer. In this way, they can control a computer cursor or, in few cases, produce speech. Recently, this field has taken some strides toward real practical applications. About 25 clinical trials of BCI implants are currently underway. And this year MIT Technology Review readers have selected these brain-computer interfaces as their addition to our annual list of 10 Breakthrough Technologies.

ChatGPT's built-in image generation feature is now available to everyone. OpenAI CEO Sam Altman said last week that the company is delaying its rollout to free tier "for a while," because the tool was way more popular than they had expected. But the company made the feature available to free users over the weekend, allowing them to generate images from within ChatGPT and without having to switch to OpenAI's DALL-E generator. Prior to its rollout to the free tier, the tool was only available to Plus, Pro and Team subscribers. Altman previously said that free users will get a limit of three images per day.

A March 20 article in The Atlantic served as the letter's impetus. It reported that Meta had used LibGen, a pirated collection of over 7.5 million books, to train its AI models. Anyone on the internet over the last few weeks has likely seen videos of distraught authors learning that their work is available on the database (and potentially used by Meta without their permission). A lawsuit in the US alleges Meta CEO Mark Zuckerberg approved the use of LibGen's data to train its AI. The lawsuit's plaintiffs include writers Sarah Silverman and Ta-Nehisi Coates.

Despite Google's model's speed, it took Imagen 3 about 10 times longer than HART to generate the picture, which shows the pace of HART. I have tested most of the text-to-image models on the market, and HART is the quickest.

Generative AI's capability to sift through data and produce code and narratives or provide analysis of a situation is well-known. However, its potential role as an assistant -- through which one can bounce off ideas or come up with new ideas -- is still being uncovered. Only about 15% of 1,400 managers surveyed by Capgemini use AI in their daily work, report Elisa Farri and Gabriele Rosani (both with Capgemini Invent's Management Lab) in their latest book, HBR Guide to Generative AI for Managers. Managers are not yet aware of how gen AI can help them lead teams, ideate, and manage. When employed as a co-pilot, gen AI becomes an efficient collaborator, handling a wide range of administrative, communication, and operational tasks, according to Farri and Rosani.

My in-laws own a little two-bedroom beach bungalow. It's part of a condo development that hasn't changed much in fifty years. The units are connected by brick paths that wind through palm trees and tiki shelters to a beach. Nearby, developers have built big hotels and condo towers, and it's always seemed inevitable that the bungalows would be razed and replaced. But it's never happened, probably because, according to the association's bylaws, eighty per cent of the owners have to agree to a sale of the property.
