• A former Nvidia engineer said anyone looking to upskill for AI needs to start by building.
• “Doesn’t matter what you build, as long as you do it end to end,” Chip Huyen told Business Insider.
• Huyen said in addition to building, engineers should master systems thinking.

A former Nvidia engineer says people looking to stay competitive in the age of AI need to start building now.

“Doesn’t matter what you build, as long as you do it end to end: starting from an idea and deploying it so that a friend can use it,” Chip Huyen, an AI researcher who worked on Nvidia’s NeMo platform and taught machine learning at Stanford, wrote to Business Insider.

Huyen’s advice extends beyond her fellow AI researchers and engineers. She said when she holds workshops for companies, it’s incredible to see what people without even a coding background can do, thanks to AI coding agents.

“After that, they become so much more confident in themselves and also have a much better understanding of AI,” she said.

If you’re stuck figuring out what to do, Huyen says she has a simple exercise.

“For a week, note down everything that frustrates you,” she wrote in a guide she shared with Business Insider. “Why is this taking so long? Why do I have to repeat this every single time? etc. For each of these problems, try to think about how to solve it. Then pick one problem to solve.”

Learning about the foundations of AI and how it works is also important, Huyen said.

“Learning only by building is like learning a new language only by speaking,” she wrote.

That’s why it’s imperative that those looking to upskill supplement their own AI exploration by learning about the tools they’re using.

“You should also bring structure into your learning, like picking a curriculum, books, courses,” she wrote.

If you’re looking for where to start, Huyen shared a list of AI-related resources with Business Insider that she compiled when writing her latest book, “AI Engineering.”

What computer science students should do

As for those studying computer science or engineers looking to expand their knowledge base, Huyen said the best thing they can do is master systems thinking.

“Coding is just a means to an end. CS is about system thinking, using coding to solve actual problem,” Huyen said during a recent episode of “Lenny’s podcast.”

Problem-solving will never go away, Huyen said, because as AI can automate more stuff, the problems will just get bigger.”

Huyen said that AI “can help automate a lot of disjointed skills,” but combining the separate knowledge to solve problems will remain difficult. She pointed to a webinar hosted by Stanford computer science department chair Mehran Sahami and Andrew Ng, founder of DeepLearning.AI and a former founding member of Google Brain, in which the pair discussed the future of CS. At the time, Sahami said that it is “critical for students to understand the code that’s generated” by AI tools.

In talking to companies, Huyen said that she is hearing examples of senior engineers spending more time reviewing code written by junior engineers. Across tech, the fear is that more junior engineering roles will be replaced as generative AI becomes more skilled at writing code itself. That’s why developing skills can help, Huyen said.

Companies “appreciate engineers who have a good understanding of the whole systems and be able to have good problem-solving skill, are thinking holistically instead of locally,” she said.

• Target is laying off 1,000 corporate employees and cutting 800 open roles.
• The layoffs affect 8% of Target’s global headquarters team, aiming to simplify workflows.
• “The truth is, the complexity we’ve created over time has been holding us back,” Michael Fiddelke said.

Target is laying off around 1,000 corporate employees and cutting another 800 open roles, the company said Thursday.

The company said in a memo to staff that the roles being cut accounted for about 8% of its global headquarters team.

Michael Fiddelke, Target COO and incoming CEO, said in the memo that the changes were intended to help the company move faster and simplify workflows.

“The truth is, the complexity we’ve created over time has been holding us back,” he said. “Too many layers and overlapping work have slowed decisions, making it harder to bring ideas to life.”

• Rivian plans to cut over 600 jobs, affecting around 4% of its workforce.
• The layoffs come amid administrative changes affecting the electric vehicle industry.
• The removal of a $7,500 federal tax credit presents challenges for companies like Tesla and Rivian.

Rivian plans to cut more than 600 roles, according to an internal memo shared with the company on Thursday that was viewed by Business Insider.

The electric vehicle maker’s decision to lay off around 4.5% of its workforce of 15,000 comes as administrative changes loom over the EV industry.

The reduction is one of several rounds of layoffs that Rivian has conducted over the past three years.

Although EV sales in the US hit a record high in the third quarter of 2025, EV makers are facing the Trump Administration’s elimination of a $7,500 federal tax credit. Americans had until September 30 to capitalize on the tax credit before the blow hit the EV industry, affecting companies like Tesla and Rivian.

The layoffs, which were first reported by The Wall Street Journal, come as Rivian prepares to launch the R2, which is poised to be the EV maker’s cheapest SUV release to date with a target price of $45,000.

In an interview with Business Insider on Wednesday at the unveiling of Rivian’s e-bike spinoff, ALSO, CEO RJ Scaringe said the R2 is a critical moment for the company.

“I’d call it an inflection point for us to become a company of the scale we aspire to be, which is producing many millions of cars a year,” he said.

Rivian has yet to reach the same level of scale as its leading US contender, Tesla — but the company has shown potential for growth.

Earlier this month, Rivian reported 13,200 vehicle deliveries, a 32% year-over-year increase. Still, the company narrowed its 2025 delivery guidance to 41,500-43,500 vehicles, amid the end of the tax credit incentives and as it prepares for R2 production.

Read the memo Scaringe sent out to employees below:

Hi Team,

I am writing to share a difficult update.

With the launch of R2 in front of us and the need to profitably scale our business, we have made the very difficult decision to make a number of structural adjustments to our teams. These changes result in a reduction in the size of our team by roughly 4.5%.

These are not changes that were made lightly. With the changing operating backdrop, we had to rethink how we are scaling our go-to-market functions. This news is challenging to hear, and the hard work and contributions of the team members who are leaving are greatly appreciated.

To ensure we move forward with clarity, I want to summarize the areas most impacted.

• Streamlining the Customer Journey: To provide a seamless experience for our customers, we are integrating the Vehicle Operations workstreams into the Service organization to create fewer customer handoffs and clearer ownership. We are also integrating the Delivery and Mobile Operations into the Sales organization to ensure the purchase experience is as seamless as possible with a single touchpoint throughout the entire sales process and to delivery.
• Elevating Our Marketing Efforts: Historically we have had multiple functions that collectively capture what would typically be housed in a single marketing organization. We have made the decision to form a single marketing organization, and while we recruit our first Chief Marketing Officer (CMO), I will be acting as Interim CMO. Our Marketing Experiences team, led by Denise Cherry, and the Creative Studio team, led by Matt Soldan, will both report directly to me for now.

These changes are being made to ensure we can deliver on our potential by scaling efficiently towards building a healthy and profitable business. I am incredibly confident in R2 and the hard work of our teams to deliver and ramp this incredible product.

Thanks again everyone.

RJ

How to buy tickets for Louis Tomlinson’s 2026 concert tour

Original standard tickets for Louis Tomlinson’s 2026 tour are available for purchase from Ticketmaster and AXS. Availability will depend on the date, location, and demand for each show. As the tour is highly anticipated, many dates already have a limited number of original tickets remaining.

Tickets are also available from verified resale vendors such as StubHub and Vivid Seats. Depending on the demand for the specific show you are looking to attend, you may find more suitable seating options and pricing from these sites instead.

How much are Louis Tomlinson tickets?

There are still original standard tickets available for purchase in limited quantities from Ticketmaster and AXS. Prices vary depending on the location, but the general range for original tickets at present is $50 to $200. Some tour stops, such as St. Louis, Fort Worth, Washington D.C., and Philadelphia (among others), even have general admission/pit original tickets available in the range of $80 to $180, which is fairly reasonable considering standing room pit tickets often fall into the realm of over $1,000 for other artists.

Resale vendors StubHub and Vivid Seats offer similar pricing to original standard tickets, with some more options in terms of seating availability, as well as some shows which are slightly more affordable than remaining original tickets.

On StubHub, the most affordable options currently range from $36 for Tomlinson’s April 21 show in Paris to $493 for his June 3 concert in Vancouver. Vivid Seats offers similar ranges, with the most inexpensive options at $59 for the July 2 show in Independence, to $720 for the March 23 show in Hamburg. Overall, Vivid Seats has more limited availability, with many international performances unavailable on the platform, so prices tend to fluctuate more than StubHub at the moment.

There are currently no VIP ticket packages available on Ticketmaster for Louis Tomlinson’s upcoming 2026 tour.

Who is opening for Louis Tomlinson’s tour?

It has been confirmed that The Aces and The Beaches will support select dates of Louis Tomlinson’s 2026 How Did We Get Here? tour. Currently, there is no information available on exactly which dates will have what openers or about any other artists who may be supporting the tour. As the tour kickoff grows closer, however, more information is likely to become available.

Will there be international tour dates?

Louis Tomlinson’s How Did We Get Here? World Tour currently has 26 international tour dates scheduled. This includes stops in Germany, Norway, Finland, Sweden, Denmark, Poland, the Czech Republic, Austria, Italy, Spain, France, Belgium, the Netherlands, the UK, and Ireland. Louis Tomlinson also has three shows scheduled in Canada.

When did Louis Tomlinson tickets go on sale?

Presale for the How Did We Get Here? Tour began on October 8, with the general sale following on October 10.

• Betting scandals could ramp up as gambling restrictions continue to loosen, researchers say.
• The NCAA is allowing its athletes to bet on professional sports starting in November.
• “Once people start to develop problems, they gamble on everything,” one researcher said.

Get ready for more sports betting scandals.

On Thursday, the FBI arrested two current members of the NBA — Miami Heat player Terry Rozier and Portland Trail Blazers head coach Chauncey Billups — as part of a long-term investigation into illegal sports betting and poker schemes. Billups’ charge wasn’t basketball-related. Former NBA player Damon Jones was also charged.

“Terry is not a gambler, but he is not afraid of a fight, and he looks forward to winning this fight,” Rozier’s lawyer said in a statement.

Sports betting scandals have been occurring for over a century, but researchers say they could become more prevalent if US gambling restrictions continue to loosen.

“This is the tip of the iceberg — and the inevitable outcome when you rampantly legalize sports wagering,” said Lia Nower, the director of Rutgers’ Center for Gambling Studies.

Next month will see another move in that direction, as the NCAA lifts its restriction on college athletes betting on pro sports.

“The more accessible, the more acceptable gambling becomes, the more people actually do it,” Nower said.

Nower said high-risk problem gambling was three times more common in places where sports betting was legal than the national average of about 2%, citing research on New Jersey from her and her colleagues that was published in 2023.

Sports betting began to ramp up on a state-by-state basis after the US Supreme Court ruled in 2018 that a nationwide ban on sports gambling was unconstitutional. There have been several high-profile scandals since, including former NBA player Jontay Porter being banned for life from the league in 2024.

Young people — particularly young men — are especially at risk for problem gambling. The Rutgers researchers found that 19% of all 18- to 24-year-olds had a high risk of developing a gambling problem. College athletes, who will soon be allowed to bet on pro sports, are squarely in that demographic. (The NCAA banned three college basketball players last month for sports betting and is also investigating 13 former hoopers.)

“Once people start to develop problems, they gamble on everything,” Nower said.

She said that some college athletes would be tempted to bet on what they know best: college sports. And if college athletes get hooked on pro sports betting and then make it to the majors themselves, they could continue to wager on their sports, though it would be against league regulations.

It’s no secret that sports betting companies are targeting college-aged men, said Shane Kraus, an associate professor of psychology at the University of Nevada, Las Vegas, who’s the director of its Behavioral Addictions Lab.

“Look at the type of ads, who they’re sending ads to — they’re not sending them to grandma and grandpa in their 80s,” Kraus said.

The ocean of money in sports betting right now will likely lead to more gambling scandals, Kraus and Nower said.

Another wrinkle is the increased popularity of “prop” bets, where gamblers can craft player-specific wagers that athletes could influence more easily than the outcome of a game.

Once problem gambling develops, loan sharks, or those in organized crime, can enter the picture. For college athletes, there are also temptations that are seemingly less nefarious but can still lead to scandal, such as getting friends to bet on their behalf to circumvent rules.

“All of this is completely foreseeable,” Nower said of how problem gambling can turn into a sports betting scandal. “It’s like watching a car crash.”

• Servicers are sending some student-loan borrowers emails confirming their balances are wiped out.
• Borrowers eligible for the relief have completed their qualifying payments on the income-based repayment plan.
• The Department of Education previously confirmed that it would begin processing the relief.

Halloween just got a little less spooky for student-loan borrowers.

After receiving emails earlier this month that they are eligible for student-loan forgiveness, borrowers on income-based repayment plans are now seeing the relief: their servicers have zeroed out their balances and confirmed the forgiveness.

Income-based repayment plans give borrowers monthly payments based on their income, with the promise of loan forgiveness after 20 or 25 years, depending on when they first enrolled in the plan. An email from the Department of Education told eligible borrowers that their servicers would notify them when their discharges have been processed, and those notifications are now starting to trickle in.

The emails are coming after the department paused processing of IBR applications earlier this summer due to ongoing litigation over income-driven repayment plans.

“Congratulations! The U.S. Department of Education has forgiven your federal student loans,” the emails dated October 23, multiple of which were reviewed by Business Insider, said.

The email also clarified that this relief is not considered taxable income due to a 2021 provision in the American Rescue Plan that made student-loan forgiveness tax-free through 2025. Borrowers who received the Thursday emails that Business Insider viewed had forgiveness “effective” dates marking the final payments needed under the IBR plans as early as January 2025. That means that even if servicers do not finish processing the relief until next year, borrowers would not be taxed due to the 2025 effective date.

The servicers added that they notified, or will notify, national credit bureaus of the student-loan forgiveness, and that they will refund any payments made after the forgiveness effective date.

The Department of Education did not immediately respond to a request for comment from Business Insider.

The relief is a rare nugget of good news amid a tumultuous year for student-loan borrowers. Over the summer, the Department of Education paused processing of IBR applications, citing ongoing litigation regarding repayment plans that required the department to update borrowers’ payment counts. The American Federation of Teachers also sued the department earlier in the year, accusing it of failing to process borrowers’ income-driven repayment applications.

Last week, the department reached an agreement with the AFT to process forgiveness for borrowers who reached the payment threshold on income-driven repayment plans. It also agreed to allow the date the borrower made their final payment to be considered as the effective date to avoid new taxes, but it added that the Internal Revenue Service and the Department of the Treasury will have the “final say” on whether the relief is considered taxable income.

A department spokesperson previously told BI that the agreement allows it to “process legitimate loan cancellations once again for borrowers who have been making payments for the requisite number of years.”
