SPhotonix's 5D Memory Crystal technology, capable of storing data for up to 13.8 billion years, is moving towards real-world deployment with plans for glass-based cold storage systems in data centers. The technology encodes data in nanoscale structures on a fused silica glass platter using a femtosecond laser, allowing a 5-inch glass disc to hold 360TB of data. Despite slower speeds compared to existing systems, the company aims to achieve faster read and write speeds in the next few years. SPhotonix's approach focuses on licensing the media and optical platform into existing data center architectures, aiming to establish itself as a competitive storage solution.

News outlets are blocking Wayback Machine from archiving their pages — 23 outlets concerned AI companies might abuse fair use and use it to train their models

Many news outlets are blocking the Wayback Machine from archiving their pages due to concerns that AI companies may misuse fair use policies by using archived content to train their models. This move could limit access to historical news stories and crucial information in an era where misinformation is rampant and AI models can generate convincing but false answers. Notably, 23 major publications, including USA Today and The New York Times, are currently blocking the Internet Archive's crawler. While some argue that publications should handle their own archiving, a neutral third party like the Wayback Machine is crucial for maintaining accurate historical records and tracking changes in online content. Despite concerns about fair use, preventing archiving services like the Wayback Machine could have more negative consequences than benefits for society.
