• Block CTO Dhanji Prasanna says code quality has little to do with a product’s success.
• Dhanji Prasanna said engineers should focus on purpose, not perfect syntax or architecture.
• His comments come as tech leaders continue to emphasize the importance of coding in the AI era.

In most engineering circles, clean, elegant code is the gold standard, but Block’s chief technology officer said that’s overrated.

Dhanji Prasanna, the fintech company’s technology lead, said on an episode of “Lenny’s Podcast” published Sunday that “a lot of engineers think that code quality is important to building a successful product,” but “the two have nothing to do with each other.”

Perfect code doesn’t make a great product, solving real problems does, said Prasanna.

Prasanna said he learned that when he was at Google. When the company bought YouTube in 2006, Google’s engineers were horrified by the video site’s codebases and “how terrible their architecture is.”

Yet YouTube, not Google’s Google Video, became one of the most successful products in the company’s history, Prasanna said.

“It really has very little to do with how well it was architected,” he said. The real measure of the product’s success is whether it actually serves users and solves a problem for people.

“Just focus on what we’re trying to build and whom we’re trying to build for,” he said. “All this code can be thrown away tomorrow.”

Prasanna also said that it’s not important to be at the forefront of every technological trend.

“Technology is here to serve us, and if we have an important reason for being and an important purpose, then we can make it that technology serve us,” he added.

Prasanna did not respond to a request for comment from Business Insider.

Coding apocalypse?

Prasanna’s comments come as tech leaders continue to emphasize the importance of coding in the AI era.

Google’s head of research, Yossi Matias, told Business Insider last year that “everybody should learn how to code,” and the basics may be more critical than ever in the age of AI.

Bluesky CEO Jay Graber told Business Insider in July that people need to know how to code well. “If you don’t know what good code looks like, if you don’t know how to actually build a system, you’re not going to be able to evaluate its output,” Graber said.

Others, like Prasanna, have said coding is no longer crucial for success.

Salesforce’s chief futures officer, Peter Schwartz, told Business Insider in May that coding is no longer the must-have skill of the AI era. “The most important skill is empathy, working with other people,” said Schwartz in an interview with Business Insider at the Singapore tech conference ATxSummit.

As AI gets better at writing code, some product managers have speculated that AI will increasingly take on technical coding tasks and circumvent their need for engineers.

During Google’s third-quarter earnings call last year, CEO Sundar Pichai said AI generated over a quarter of the company’s new code.

• Lithuania said on Sunday that balloons flying from Belarus are forcing airport shutdowns.
• Officials said the balloons are likely for smuggling cigarettes, but still pose an air safety threat.
• Lithuania’s prime minister has blamed Minsk for allowing the balloons to “run wild.”

Balloons flying in from Belarus have prompted officials in Lithuania to close local airports for a third night in a row.

Authorities said in a statement on Sunday evening that the airspace around Vilnius Airport had been temporarily suspended, affecting some 47 flights from 9:42 p.m. to 4:30 a.m. the next morning.

“According to initial information, the decision regarding airspace restrictions was made due to balloons flying in the direction of Vilnius Airport,” the statement said.

The incident is the latest in a string of reports this week from Lithuania, a NATO member, that helium-filled balloons have been entering its territory from the Belarusian border.

In a statement on Saturday, Lithuanian Prime Minister Inga Ruginiene said a “large group of smuggling meteorological balloons” had been launched from Belarus and into her country.

Another airport, in Kaunas, had to be closed as a result, she said.

The prime minister added that the balloons are likely used for smuggling cigarettes, but blamed the Russia-aligned leader of Belarus, Alexander Lukashenko, for allowing them to “run wild.”

In a separate statement on Sunday, Rugiene said that Lithuania was temporarily closing its borders with Belarus as its security council meets on Monday to discuss next steps.

Lithuania has been dealing with balloons from Belarus for some time. In September 2024, border authorities said 250 balloons had crossed over in a single month.

However, the country has been raising the alarm more frequently over such incidents over the last year, as the Baltic states report repeated airspace violations from Russia, which counts Belarus among its closest allies.

Lithuanian authorities said this week’s first balloons started showing up days before and had already prompted an earlier airport closure. On Wednesday, local officials issued a statement saying that they detected “several hundred markers” in a single night that could have been smuggling balloons.

These are often equipped with GPS trackers and SIM cards that allow their cargo to be tracked, the statement said.

“This year, more than 100 people have been arrested for air smuggling, 20 of whom have already been convicted,” it added.

The statement also called on tech companies and defense contractors to pitch solutions for tracking and destroying such balloons.

More broadly, European NATO has been on edge after a series of drone incursions over Poland in September, many of which were said to involve Russian Gerberas flying through Belarus.

Other NATO allies, such as Denmark, have reported drone incursions over their airports in the weeks since.

Balloon incursions have happened elsewhere, too. In the summer of 2024, South Korea accused North Korea of floating over hundreds of trash-filled balloons, spreading garbage across the greater Seoul region as a gray warfare tactic.

The press team for Lukashenko’s office did not respond to a request for comment sent outside local business hours by Business Insider.
