LONDON — Beatles singer-songwriter Paul McCartney told the BBC that artificial intelligence was used to “extricate” and clean up the vocals of former bandmate John Lennon from an old recording, allowing them to feature in an upcoming track.

“It’s a very interesting thing, you know. It’s something we’re all sort of tackling at the moment and trying to deal with,” McCartney told the BBC’s “Today” program when asked about AI.

McCartney said “Lord of the Rings” director Peter Jackson — who in 2021 released an eight-hour documentary called “The Beatles: Get Back” featuring colorized, cleaned-up archive footage of the band — was able to “extricate” Lennon’s voice “from a ropey little bit of cassette.”

AI was used to identify Lennon’s vocals as distinct from instrumentals and background interference.

“So when we came to make what will be the last Beatles record, it was a demo that John had that we worked on, and we just finished it up. It will be released this year,” McCartney said.

“We were able to take John’s voice and get it pure through this AI, so that then we could mix the record as you would normally do. It gives you some sort of leeway.”

The BBC said it is expected to be a Lennon song from 1978 called “Now And Then,” which McCartney has in the past expressed a desire to “finish.” Lennon was murdered in 1980.

On his recent tour, which included a headline slot at Glastonbury festival, McCartney performed songs with a cleaned-up Lennon vocal track, as well as a video of the artist on stage with him.

Industry experts have been reflecting on the potential for the latest technological advances within the music industry, along with the ethics of posthumously recreating artists.

ABBA’s Björn Ulvaeus, whose show “ABBA Voyage” uses motion capture and advanced real-time graphics to have the band perform as de-aged digital avatars, previously told CNBC he had concerns about the creation of “deep fakes.”

“There’s a good side to it and then a scary side, and we’ll just have to see where that leads,” McCartney told the BBC.

China’s Baidu says it’s running 250,000 robotaxis a week — same as Alphabet’s Waymo did this spring

China's Baidu says it's running 250,000 robotaxis a week — same as Alphabet's Waymo did this spring

Chinese tech company Baidu announced Monday it can sell some robotaxi rides without any human staff in the vehicles.

BEIJING — As Baidu ramps up its robotaxi operations worldwide, fully driverless weekly rides as of Oct. 31 have now surpassed 250,000 orders, according to a spokesperson for the company’s driverless car unit Apollo Go.

That’s on par with what Waymo reported in late April for its weekly paid U.S. rides. When contacted by CNBC, Waymo did not have a new specific figure to share. The Alphabet-backed robotaxi operator primarily operates in San Francisco and Los Angeles in California and Phoenix, Arizona. Waymo partners with Uber in Austin and Atlanta.

The ramp up in Baidu’s robotaxi capabilities comes as Chinese and U.S. companies have been competing for leadership in advanced technology, including artificial intelligence, electric cars and autonomous driving.

It was not clear for how long Apollo Go has been operating 250,000 rides a week. For the quarter ended June 30, the company averaged about 169,000 rides a week based on CNBC calculations of the 2.2 million fully driverless robotaxi rides disclosed for the period.

Baidu’s Apollo Go primarily operates robotaxis in Wuhan and parts of Beijing, Shanghai and Shenzhen in mainland China. The company is also expanding to Hong Kong, Dubai, Abu Dhabi and, most recently, Switzerland. Robotaxis typically must undergo phases of public testing before local regulators allow companies to charge fares.

Apollo Go said it has received 17 million robotaxi ride orders to date, and that its cars have driven 240 million kilometers (149 miles), with 140 million fully driverless rides.

On safety, Apollo Go disclosed on average there has been one airbag deployment incident for every 10.1 million kilometers driven, but so far there’s has not been any major accident involving human injury or death.

Baidu is scheduled to next release its quarterly results on Nov. 18 before U.S. market open. The company is set to hold its annual tech conference in Beijing on Nov. 13.

Weekly robotaxi figures from Chinese rivals Pony.ai and WeRide were not immediately available. Waymo did not immediately respond to a request for an update to the figures shared in April.

CNBC Daily Open: AI trade frenzy seems driven by a 'virtuous' cycle

Traders who shorted the S&P 500 — essentially, betting that it would go down — last month were in for a rude surprise. The broad-based index ended the month 2.3% higher, defying “Octoberphobia,” a term that arose because of the market crashes in 1929 and 1987 that happened during the month.

The Nasdaq Composite had an even better month than the S&P 500. The tech-heavy index climbed 4.7%, giving a hint of what helped ward off the arrival of any ill omens: the technology sector.

On Friday, Amazon shares popped 9.6% on robust growth in its cloud-computing unit and as CEO Andy Jassy pointed to “strong demand in AI and core infrastructure.” The news pushed up other artificial intelligence-related stocks such as Palantir and Oracle too.

AI’s ascent in the market wasn’t a one-day event. In October, Nvidia, the poster child of AI, became the first company to reach a valuation of $5 trillion, with CEO Jensen Huang describing the technology as having formed a “virtuous cycle” in which usage growth will lead to an increase in investment, in turn improving AI, which will boost usage, which will… You get the idea.

Indeed, during their earnings disclosures last week, Big Tech companies announced dizzying increases in their capital expenditure, most of which will likely go toward AI infrastructure.

All that is to say that the enthusiasm over AI looks, for now, less like the immediate sugar rush of a candy bar (and the subsequent crash), and more like the sustained energy boost from a fiber-rich pumpkin.
