Chatbots Can Go Into a Delusional Spiral. Here’s How It Happens.

NEW from @kashhill.bsky.social and me:

Over three weeks in May, a man became convinced by ChatGPT that the fate of the world rested on his shoulders.

Otherwise perfectly sane, Allan Brooks is part of a growing number of people getting into chatbot-induced delusional spirals. This is his story.

CALLOUT: Marketplace is looking for Canadians who think they have Canada's worst commute. Ideally we're looking for very specific routes, roads and intersections in your city that drive you crazy to investigate for a potential episode next season.

Shoot us an email at marketplace@cbc.ca!

The price of patriotism: Have grocers boosted the cost of some iconic Canadian brands? | CBC News Marketplace analyzed price data from one downtown Toronto Loblaws store from the start of the year to find out if products that are β€˜Prepared in Canada’ have increased in price

From @bobbyhristova.bsky.social and I this weekend: we took a look at a few iconic Canadian products that have increased in price since the trade war began, and ask experts: is this a maple tax?

of course, as many things in our world are, it's complicated!

Marketplace found up to 1 in 3 groceries get labelled as Canadian. Customers say they're skeptical | CBC News To find out how often grocery stores are labelling products with Canadian symbols, Marketplace collected data from the websites of some of the country’s largest grocers.

our first in the series took a look at the scope of those Canada flags in the grocery story, and how they're pretty confusing for consumers!

Part of the magic of Bluesky for me right now is rediscovering Twitter folks that I had forgotten about after leaving the platform more than a year ago. Like Gurdeep!

I love this protest game for Toronto bike lanes by @omarieclaire.bsky.social so much, having a lot of fun dying repeatedly

MPs to probe how human smuggler obtained new passport while barred from having one | CBC News A House of Commons committee voted Thursday to probe how an admitted human smuggler received a new Canadian passport through Service Canada after he was forced to surrender a previous travel document under court-imposed conditions of release.

The Standing Committee on Citizenship and Immigration agreed to hold two days of hearings on the issue with testimony from Immigration Minister Marc Miller and Public Safety Minister Dominic LeBlanc, along with reps from RCMP and CBSA.

β€œpotato cartel” is just a fantastic (alleged) name for this.

had a Marketplace viewer write in to tell us the show should be on Bluesky, and it made me genuinely excited about the potential this platform holds! i've so missed having a space like this.

I made this starter pack less than a month ago & added every Canadian journalist I knew of on BlueSky at the time.

Since then, I've been unable to keep up with all the new arrivals!

The pack is now FULL (150 people!)

Is it worth me creating a 2nd one? I know other packs are out there now too.
