How has the recent turmoil within the OpenAI offices changed your plans to use GPT in a business process or product in 2024?
Increased uncertainty means we are more likely to evaluate alternative AI chatbots and LLMs.
No change in plans, though we will keep an eye on the situation.
With Sam Altman back in charge, we are more likely to go all-in with GPT and LLMs.

Researchers Unveil Billion-year Data Storage

A new technology being developed at the University of Southampton can store up to 360 terabytes of data per disc. That’s more than 75,000 times the storage capacity of a DVD and more than 7,000 times the capacity of a Blu-ray disc.

Even better than its jumbo capacity, however, is its tenacity.  At room temperature, the discs are expected to last 13.8 billion years, which is more than three times the age of the Earth. Plus, it can withstand heat up to 1,800 degrees Fahrenheit (1,000 degrees Celsius).

Back in 2013, the team’s leader explained that “We are developing a very stable and safe form of [high-density] portable memory using glass,” noting it could be “highly useful for organizations with big archives.” Their latest research was presented last week in San Francisco at The International Society for Optical Engineering’s Photonic West Conference.

The specs sound like technology from a science fiction story. Using something called an ultrafast laser, the researchers wrote data onto fused quartz, which has a much higher melting point than regular glass.

In past experiments, the laser split into 256 smaller beams, with each laser-imprinted spot storing 3 bits of information. The dots effect how light passes through the glass in a way that can be read using an optical microscope and a polariser, described as similar to the effect of sunglasses. It’s considered five-dimensional data storage because information is represented by the values in three dimensions, as well as the orientation of the data, and the strength of the light.

“Thrilling,” is how one of the group’s professor’s described the innovation. “This technology can secure the last evidence of our civilization: all we’ve learned will not be forgotten.”

For that reason, they’re calling it “the Superman memory crystal,” and they’ve already saved copies of the bible and the Magna Carta they believe could outlive the human race. “We can encode anything,” one of the project’s graduate students told The Verge. “We have the ability to store the culture, language, and essence of the human race in a simple piece of glass. For future civilizations — or whatever else is out there.”

Their next step? Commercialization of course, which involves locating industry partners, and developing their technology for everyday use. Even back in 2013, the team was writing in a report (PDF) that “We experimentally demonstrated the recording and read-out processes of 5D optical data by femtosecond laser writing.”

“This demonstration is a crucial step towards commercialization of ultrafast laser based optical data storage.”
