I just watched Biggie Smalls perform ‘live’ in the metaverse

For a moment on Friday, Biggie Smalls was the only man on stage. A spotlight shone on him in his red velvet suit, and amid pre-recorded cheers, he rapped the lyrics to “Mo Money Mo Problems,” swiveling to the beat in his orange sneakers.

You wouldn’t be wrong to be confused. Smalls died in 1997, leaving an outsize musical and cultural legacy as one of the greatest rappers of all time. But he was in fine form on Meta’s Horizon Worlds: heaving between stanzas, pumping his fist rhythmically, and seeming very much alive.

But Smalls’s hyper-realistic avatar is not just an impressive technical feat. It is also a crucial test of two big questions we’ll soon face if metaverse platforms gain traction: whether people will pay to see an avatar of a dead artist perform, and whether that business is ethical.

How to spot AI-generated text

This sentence was written by an AI—or was it? OpenAI’s new chatbot, ChatGPT, presents us with a problem: How will we know whether what we read online is written by a human or a machine?

ChatGPT generates remarkably human-sounding answers to questions that it’s asked. The trouble is, it’s merely predicting the most likely next word in the sentence. It hasn’t a clue whether something is correct or false, and confidently presents information as true even when it is not. Despite that, the internet is increasingly being flooded with AI-generated text.

We’re in desperate need of ways to differentiate between human- and AI-written text in order to counter potential misuses of the technology, and researchers are developing tools to do exactly that. But the rapid speed of AI development means we’re constantly playing catch up. Read the full story.

The big story

Stitching together the grid will save lives as extreme weather worsens

July 2022

The blistering heat waves that set temperature records across much of the US this summer strained electricity systems, and threatened to knock out power in vulnerable regions of the country. While the electricity largely stayed online, heavy use of energy-sucking air-conditioners and the intense heat contributed to scattered problems and close calls.

The nation’s isolated and antiquated grids are in desperate need of upgrades. One solution would be to more tightly integrate the country’s regional grids, stitching them together with more long-range transmission lines, allowing power to flow between regions to where it’s needed more urgently. However, that’s a mission that’s fraught with challenges. Read the full story.
