At every CES I've ever been to, there's been one or two gadgets promising to boost your mental health. In recent years, the number of companies making forays into this space has grown, and will likely continue to do so in the future. Could it be, much like the number of people wearing heart-monitoring wearables today, everyone will be strapping an EEG to their skulls a decade or so down the line? It's more likely than you think, so it's worth asking what these devices are good for, what benefit they could bring, and where does the science end and the hype begin.
An Electroencephalogram (EEG) is a clinical tool to monitor the electrical activity of our brains. Put very simply, our minds are constantly moving ions around, and when they reach the scalp, it's possible to measure those ions. By placing electrodes on the scalp, you can record the changes in voltages pushed out by our brains more or less in real time. These voltages are commonly grouped into categories, which are often described as brain waves. Each one represents a different state of mind: Gamma (hard thinking), Beta (anxious or active), Alpha (relaxed), Theta (creative, or dreaming) and Delta (asleep).
Professor Karl Friston at University College London is one of the world's most influential neuroscientists and an expert in brain imaging. He explained that these technologies can be used to diagnose issues both in the structure and function of the brain. And while there are many technologies which can look at how our brains work, "we're a long way away from understanding the brain like we understand the heart." Broadl

 Even without any announcements from Apple, CES dominated tech news this week with a host of upcoming products and technologies being demonstrated at the annual expo in Las Vegas.

 X may soon provide more insight into how its algorithm works. On Saturday, Elon Musk posted on the platform to say that the company "will make the new X algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days."
X's recommendation algorithm has been the subject of investigations by France and the European Commission, the latter of which recently extended through 2026 a retention order that it sent to the company at the beginning of last year. And scrutiny into the platform, along with demands for accountability, have only increased after its chatbot, Grok, was caught generating CSAM at users' requests and continues to be used to digitally undress women nonconsensually.

Bose recently announced the pending end of cloud support for its SoundTouch line of home speakers. This will, in effect, turn the smart speakers into dumb speakers as they will no longer have access to many features and any related software updates. Well, there's a spot of good news for SoundTouch owners. The company is turning to an open source model for the software, allowing third parties to keep the music playing.
The company has already begun mailing out the API documentation to customers so "independent developers can create their own SoundTouch-compatible tools and features." This will take some time, so Bose is also extending the end-of-life (EoL) date for the SoundTouch speakers. They were set to stop receiving cloud updates in February, but that has been moved to May 6.
It made a couple of other changes to make life a bit easier for SoundTouch owners. The speakers will still be able to use AirPlay and Spotify Connect after EoL, which was so
