Web crawlers scan and catalog sites all over the internet and, in the AI era, use that data to train chatbots. We’ll talk about why The New York Times is trying to put a stop to crawlers from the AI company Perplexity. We’ll also discuss the record share of venture capital dollars flowing into the AI sector and the difficulty of attracting investment for startups without those two magic letters. Plus, the ups and downs of SpaceX, owned by Elon Musk. Marketplace’s Meghan McCarty Carino spoke with Jewel Burks Solomon, managing partner at Collab Capital, for her take on all this for our weekly segment “Marketplace Tech Bytes: Week in Review.”

Vice President Kamala Harris sat for her first interview on Fox News Wednesday as the Democratic presidential candidate continued her media blitz ahead of the November election. And while it’s generating plenty of headlines, these kinds of big interviews just don’t hold the power they used to, according to Nick Quah, a podcast and culture critic at New York Magazine who’s been following the candidates’ interviews on the alternative media circuit. Marketplace’s Meghan McCarty Carino spoke with Quah about how Kamala Harris’ appearance on more internet-native shows like the podcast “Call Her Daddy” or Donald Trump’s appearances on various “bro-centric” shows like Logan Paul ‘sYouTube channel represent a notable media shift compared to previous elections.

After years of hype, Tesla finally debuted a robotaxi called the Cybercab last week. CEO Elon Musk has been making and breaking promises about Tesla’s autonomous vehicle for years. So, did the debut of the Cybercab finally deliver? Andrew Hawkins, transportation editor for The Verge, tells Marketplace’s Meghan McCarty Carino what the Cybercab unveiling means for Musk and for Tesla.

Online misinformation about Hurricanes Helene and Milton, and about the relief response from the Federal Emergency Management Agency have surged in recent weeks, including false narratives of aid being withheld from victims for their political beliefs and aid being stolen by undocumented immigrants. Marketplace’s Kimberly Adams spoke with Ethan Porter, professor of media, public affairs and political science at George Washington University, about why there’s been so much misinformation about these natural disasters and FEMA’s relief response.

TikTok has a lot going on legally these days. Last week, it saw a fresh round of lawsuits alleging the short-form video app harms children. And then there’s the federal law that could ban the app if ByteDance, its China-based owner, doesn’t divest by January. TikTok has sued to block that law. Oral arguments in TikTok Inc. v. Merrick Garland were heard in the U.S. Court of Appeals for the District of Columbia Circuit in September. The company is joined by eight TikTok creators as plaintiffs in the case, and one of them is Talia Cadet. She has nearly 140,000 followers on TikTok, where she produces lifestyle videos focused on her love of books and travel. She talked with Marketplace’s Meghan McCarty Carino about the case.

TikTok is facing yet another legal challenge. This week, attorneys general from 13 states plus Washington, D.C., sued the short-form video app, alleging that it harms children. We’ll be digging into the latest lawsuits on today’s Marketplace “Tech Bytes: Week in Review,” our roundup of the week’s top tech headlines. Like the so-called Godfather of AI who is sharing the Nobel Prize in physics. Plus, the U.S. government is weighing what to do about Google after its search business was ruled a monopoly earlier this year. Marketplace’s Meghan McCarty Carino is joined by Maria Curi, tech policy reporter at Axios, to break down these stories.

The new kid on the block of social media, Meta’s Threads, hit 200 million active users in August. When it launched in the summer of 2023 as a rival to the platform formerly known as Twitter, Meta said the app would eventually be integrated into the so-called fediverse. This “federated universe” is the most prominent example of a decentralized social network in which users can join any affiliated platform and interact with content from all the others. Recently, Meta took some steps to integrate Threads into this ecosystem, and Will Oremus, tech news analysis writer for The Washington Post, has been following the developments.

A lot of personal data – stuff like your home address, phone number, marital status and more – is out there on the internet. Anyone can buy it from sites like Whitepages, PeopleFinders or Intelius, which aggregate data from public records and social media. You can contact each of these “people search” sites and request they take down your information, but it’s a bit of a game of whack-a-mole. Naturally, a whole industry of data-removal services has sprung up. For a price, they promise to do the dirty work for you. But do they deliver? Marketplace’s Meghan McCarty Carino spoke to Yael Grauer, a researcher at Consumer Reports, who recently looked into the efficacy of the data-removal industry.

Until about a decade ago, independent cybersecurity researchers in the U.S. weren’t allowed to examine voting machines for potential vulnerabilities. But that ban was essentially lifted in 2015. Two years later, DEF CON — one of the largest hacker conventions — decided to invite hackers, cybersecurity researchers and election officials to find those flaws during its annual Voting Village event. Marketplace’s Kimberly Adams spoke with Catherine Terranova, executive director of Voting Village, about how they balance the well-intentioned work of finding vulnerabilities before bad actors do and the problem of misinformation around the security of voting machines.

It’s been more than 15 years since the digital currency bitcoin was launched, going from a fringe phenomenon in the dark corners of the internet to an asset traded on Wall Street. But the identity of bitcoin’s creator, known by the pseudonym Satoshi Nakamoto, has remained a mystery wrapped in a cryptographic enigma. Now, investigative filmmaker Cullen Hoback may have cracked the case. His last HBO series “Into the Storm” uncovered the origins of the QAnon conspiracy theory. In his new documentary, “Money Electric: The Bitcoin Mystery,” Hoback sets out to answer the elusive question: Who is Satoshi Nakamoto? To prevent any spoilers, we’ll keep his conclusions secret.
