Block, the financial technology company co-founded by Jack Dorsey, has laid off over 4,000 employees in a sweeping, AI-driven restructuring. The cuts were announced directly by Dorsey in a company-wide email, catching employees, including those actively engaged in critical projects, by complete surprise.

Ivan Ureña-Valdes, a data analyst with nearly four years at the company, was interviewing a candidate when the notification arrived. "A coworker messaged me: 'Hey, are you okay?' My heart started racing. I knew from that message it meant that I was probably getting laid off," Ureña-Valdes told Business Insider.

Sudden Termination During Critical Work

Ureña-Valdes, who described himself as the sole provider for his family, was in the middle of working on two of the largest projects of his tenure at Block. He had previously survived three separate rounds of layoffs, some company-wide, and was confident his performance was not a factor. "For 4,000-plus people to be cut without anybody knowing, that tells me decisions were made very high up," he stated.

The CEO's email explicitly cited artificial intelligence and a strategic vision for its integration as the primary reason for the job cuts. Ureña-Valdes expressed appreciation for this honesty, noting it was "much fairer of him to come straight out and say why it happened." He also acknowledged the "generous severance and benefits" provided.

AI's Encroachment on Data Roles

The layoffs follow a period of intense internal promotion of AI tools by Dorsey. Ureña-Valdes reported using these tools daily and observed a rapid automation of core data analyst tasks. "So much of the data analyst world is finding the right dataset, writing something that will allow you to pull the data set that you want, and then generating output. Every single one of those steps is significantly faster and easier because of AI," he explained.

He pinpointed the launch of Anthropic's Opus 4.5 model late last year as a moment that crystallised the technology's disruptive power, leading to a "whoa" moment regarding its capabilities.

Industry-Wide Pessimism and Personal Uncertainty

Looking forward, Ureña-Valdes is pessimistic about the broader impact, predicting "more disruption and more of these types of cuts will probably come at other companies." He views the replacement of human roles by AI as "inevitable" in a US economy prioritising growth and financial efficiency.

While optimistic about finding another role in the data field, he is nervous about the increased industry competitiveness. "Some people are getting really, really high salaries at AI companies, while tons of people at Block are getting laid off," he noted, mourning the loss of a remote role with fair pay and strong colleague relationships.
