Canada hits the US with tariffs as trade war intensifies

Seems like Canada isnβt afraid to put one of the worldβs largest trading relationships on ice. Canada slapped tariffs of up to 50% on American exports Tuesday, responding to US duties that kicked in over the weekend.
Heated rivalry
Following days of the two countries playing the blame game over failed trade negotiations, Canada decided to strike back at the US:
Canada plans to impose tariffs of 15%, 25%, and 50% on $20 billion worth of US-made goods, matching American duties βdollar for dollar.β
Roughly 700 products (including chainsaws, cheese, and motorcycles) will be affected when the tariffs take effect after Labor Day.
Theyβre strategic: The tariffs only cover 7% of US exports to Canada, but measures like seafood duties could disproportionately hurt Maineβ¦ where Republican Sen. Susan Collins is locked in a tight reelection battle.
So, is Canada making the right call?
Experts say βmeh.β The US is the nationβs largest trading partner by a wide margin, accounting for roughly 72% of all Canadian exports. That puts Canada in a pretty fragile position. According to economists:
Tariffs on food, clothing, and other goods could make everyday purchases more expensive for Canadians.
Also, the countryβs greater dependence on US trade means Canada will feel more of the economic consequences.
The potential drawbacks arenβt stopping them: Ontario Premier Doug Ford said he and Prime Minister Mark Carney discussed a tax on electricity exports to the US, which could raise energy costs for Americans.
Can the trade war still be averted? Itβs possible. Despite the escalating tensions, Carney and senior Trump administration officials have signalled theyβre willing to resume trade talks.
π Why does this matter? Americans will likely see higher prices on a wide range of everyday items as US businesses pay higher costs for Canadian goods and materials and pass some of those increases on to shoppers. Industries dependent on Canadian customers could especially take a hit if they respond by buying fewer American goods.

China hacked into NASA, the DOJ, the Senate, and more

The Justice Department and FBI said they disrupted a multi-year Chinese hacking operation that allegedly breached or targeted some of the nationβs most sensitive government networks.
What happened?
The hacking operation dates back to at least 2018, and the group responsible, known as QTFY, has been selling stolen data and offensive hacking services to Chinaβs Ministry of State Security and the People's Liberation Army. See more about the group here (scroll to page four).
US officials say QTFY broke into NASA, the Federal Reserve, the US Senate, and the Departments of Justice, Energy, and Health and Human Services.
Their attack also extended to hospitals, telecommunications companies, defense contractors, and other organizations.
How did they just get caught now? QTFY disguised its attacks by infecting vulnerable devices (mostly citizensβ routers) and directing activity through them, making the hacks appear to come from somewhere else. The Justice Department said it has since shut down key parts of the operation, though experts warn the hackers could eventually rebuild it.
What was QTFY trying to do? Cybersecurity experts say much of the activity appears focused on espionage (gathering intelligence and stealing valuable data) rather than immediately shutting systems down, which could give them a leg up in a future confrontation with the US.
π Why is this important? The plot shows foreign cyberattacks are increasingly targeting the systems Americans use every day, and that even ordinary routers and smart devices can be secretly hijacked to facilitate attacks. The development may make home cybersecurity part of the USβ broader national-security defenses.

Teen employment seems to be rebounding

If your barista giggled when your bill came out to $6.70, now you know why. After decades of decline, more American teenagers are beginning to work summer jobs again.
Itβs a noticeable shift
But it's still nowhere close to previous generations. More than half of American teens routinely worked during the summer through the 1990s, with the rate peaking at 58% in 1978.
Regardless, teen employment is going up this summer:
Over 6.2 million teens (35.5%) aged 16-19 are working.
That's up from 33.8% last summer.
What jobs are they working? Restaurants, hotels, and other hospitality businesses account for 32% of working teens, while retail accounts for another 21%. Combined, those two industries employ more than half of the nationβs teenage workforce.
The types of jobs available to them are changing too: An average of 701,000 teens worked in transportation and material-moving jobs this summer, up from 539,000 last year. Meanwhile, office and administrative employment among teens fell from 563,000 to 449,000.
Summer jobs have been dropping for decades
While teen employment may be rising now, itβs typically been headed in the opposite direction:
Teen employment took its biggest hit after the Great Recession, falling to 29.6% in 2010 and 2011.
The pandemic dealt another blow by shutting down restaurants and tourist destinations.
Why isnβt it higher now? Today, teens face fewer entry-level openings, leading many to spend their summers volunteering or taking college courses.
π Why should you care? Rising teen employment could give restaurants, retailers, and other businesses a larger pool of workers to fill seasonal and entry-level positions, potentially easing some staffing and wage pressures.

Bill Gates is worried about the future of AI

Bill Gates rang the alarm bell on AI earlier this week, saying the technology could eliminate large numbers of jobs faster than workers and governments can adapt.
This would be the worst possible time for humans to lose their critical thinking skills,
Whatβs the big concern?
In a lengthy essay published Wednesday, the Microsoft co-founder said AI could transform the βsocial, political, and economicβ atmosphere in the US within roughly a decade. Gates said:
Many jobs could disappear permanently, rather than temporarily during an economic crisis.
Society is dramatically underestimating how disruptive the transition could be, writing that βthere is no planβ for managing the economic consequences.
The potential disruption from AI and robotics could be different from past technological shifts, which unfolded over generations and mostly produced tools that still depended on human thinking rather than replacing it.
Whatβs his solution? Gates proposed taxing AI use, protecting some jobs exclusively for humans, and increasing global cooperation on regulation, especially between the US and China.
Itβs not all bad: Gates remains optimistic about AI's ability to improve medicine, science, and productivity.
π Why is this important? If AI allows companies to produce more with far fewer workers, Americans could face fewer job openings, greater competition for remaining positions, and weaker bargaining power even as businesses become more productive.

Meta settles landmark teen addiction trial
Godofredo A. VΓ‘squez / AFP via Getty Images
Meta agreed to a settlement worth as much as $18 billion over allegations that it intentionally designed its platforms to addict children and illegally collected data from users under 13.
The impact across the tech giantβs platforms will be significant.
Big changes are coming to Insta and Facebook
The settlement ends the historic trial that began in California last week (see previous briefing) and is a big win for the dozens of states involved. Under the agreement:
Meta will pay 47 states $12.7 billion over the next decade.
It will have to pay an extra $5.3 billion if Snap, TikTok, and YouTube enforce similar protections and make a matching $5.3 billion payment.
The money will all reportedly go to youth online safety programs.
As part of the settlement, Meta agreed to make massive changes to Instagram and Facebook:
Teens can only use the platforms for two hours a day.
Users aged 13 to 17 will be blocked from using the apps between midnight and 6 am.
Push notifications for teens will be disabled between 8 am and 3 pm on school days.
Thatβs not all: Meta says it will strengthen parental controls, restrict content involving bullying, eating disorders, and self-harm; kids will also no longer see likes and reactions and will be blocked from using βextreme makeup filters.β
This isnβt good for Meta
Children and teens spend a lot of time brainrotting on their platforms, and these restrictions could heavily impact their business.
Meta said Wednesday it expects the agreement to result in around $10 billion in legal expenses this quarter. However, thatβs far less than the original $1.4 trillion the states were seeking, which likely wouldβve bankrupted the company.
Whatβs the big picture? The payout represents only a fraction of Metaβs $201 billion in annual revenue, but itβs the largest state consumer protection settlement since Big Tobacco paid over $206 billion in the 1990s.
π How does this affect you? Metaβs $18 billion settlement will dramatically change how kids use Instagram and Facebook. More importantly, the agreement could ripple to other platforms by pressuring TikTok, YouTube, and others to adopt similar protectionsβ¦ or risk becoming the next targets of lawsuits.
