The Download: Twitter may only last weeks, and Meta’s unforced AI error

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.

Former Twitter employees fear the platform might only last weeks

Recently-departed Twitter staff have told MIT Technology Review they worry that the platform has weeks to live based on current staffing levels, mass resignations overnight, and the morale of the few who remain.

The company's former employees estimate that 75% of its remaining workers plan to quit after Elon Musk gave them an ultimatum of adopting extremely hardcore" working practices or to accept three months severance, a widescale revolt which looks like it will leave Twitter sorely short of key staff in the days to come.

For those who escaped the madness earlier, either through layoffs or being fired for insubordination, it's a troubling development. They're concerned that there's just not enough technical expertise to keep the site running, and that unless drastic changes are made, and soon, Musk's actions will signal the end of Twitter.

Why Meta's latest large language model only survived three days online

On 15 November Meta unveiled a new large language model called Galactica, intended to assist scientists. But instead of landing with the big bang Meta hoped for, Galactica has died with a whimper after three days of intense criticism. Yesterday it took down the public demo that it had encouraged everyone to try out.

Meta's mis-step-and hubris-shows once again that big tech has a blind spot about the severe limitations of large language models.There is a large body of research that highlights the flaws of this technology, including its tendency to reproduce prejudice and assert falsehoods as facts.

However, Meta and other companies working on large language models, including Google, have failed to take it seriously. Read the full story.

Who's responsible for climate change? Three charts explain

Leaders at the annual UN climate conference are still in the thick of negotiations, working to find a path forward to cut emissions, as well as to address climate impacts that are already occurring.

Central to these negotiations is a question: who is responsible for climate change? The issue is complicated, but our charts might help to illuminate some of the answers.

I found out my biological age-and was annoyed by the result

You're only as old as you feel, or so they say. But now, you can put a precise number on your physical age, thanks to biological clocks. These tools analyze proteins in your blood, chemical markers on your DNA, or even the makeup of your gut bacteria to essentially predict how close you are to death.

It's a tantalizing idea. So when a company offered Jessica Hamzelou, our senior biotech reporter, the chance to find out her own biological age, she took it. But, as she found out, a vegetarian diet and regular yoga practice haven't turned the clock back for her as much as she hoped. Read the full story.

The big story

Behind the painstaking process of creating Chinese computer fonts

Bruce Rosenblum switched on his Apple II. A green grid appeared, 16 units wide and 16 units tall. This was Gridmaster," a program Bruce had cooked up to build one of the world's first Chinese digital fonts. He was developing the font for an experimental machine which was among the first personal computers to handle the Chinese language.

He had a long list of tasks ahead of him. At the time, in the late 1970s and early 1980s, there were no personal computers being built in China. So to make a Chinese" PC, Rosenblum's team was reprogramming an Apple II to operate in Chinese, which required programming both an operating system and a Chinese word processor.

While the machine was never commercially released, the painstaking work that went into its development was central to a complex global effort to solve a vexing engineering puzzle: how to equip a computer to handle Chinese, and in the process, eventually make the internet accessible to one-sixth of the global population.
