Block Lays Off Nearly Half of Staff in AI Pivot
Jack Dorsey's company Block, formerly Square, is cutting nearly half of its workforce in what is being called the largest layoff in S&P 500 history. In a public letter, Dorsey urged the industry to prepare for similar restructurings as companies retool for AI-first strategies. The move is seen as a significant indicator of a broader wave of AI-driven job cuts across the tech sector.
The layoff of over 4,000 employees reduces Block's total headcount from over 10,000 to just under 6,000. The move was announced in a shareholder letter where CEO Jack Dorsey explained the company is restructuring to become "smaller" and "flatter" in its AI-first approach. Despite the significant cuts, Block reported strong financial performance, with a gross profit of $10.36 billion for the full year of 2025, a 17% increase year-over-year. The market reacted positively to the news, with Block's stock surging approximately 25% in after-hours trading following the announcement. This investor response is seen by some as a potential template for other CEOs to follow, rewarding companies that explicitly link workforce reductions to AI-driven efficiency gains. Affected US employees will receive 20 weeks of base severance pay, plus one additional week for each year of service, vested equity through the end of May, six months of health insurance, and $5,000 for transition-related expenses. Block has been investing heavily in internal AI tools, including an open-source assistant named Goose, which reportedly saves employees 8 to 10 hours per week. The company's "Intelligence-Native" strategy also includes "ManagerBot" for merchants and "MoneyBot" within the Cash App to act as a virtual COO and personalized financial assistant, respectively. This internal tooling is central to Dorsey's vision of smaller, more agile teams accomplishing more. The role of AI in software development is shifting from replacement to augmentation, with tools designed to handle repetitive tasks and boost productivity. Developers using AI-assisted coding tools have been found to complete tasks up to 55% faster. While adoption is widespread, with 80-85% of developers using AI coding assistants regularly, trust remains a significant issue, with only about a third of developers fully trusting the code generated by AI. AI is also transforming front-end development by enabling more personalized user experiences and improving workflow efficiency. AI can analyze user data to make real-time adjustments to interfaces and content, and it can help ensure design consistency and accessibility. These tools are increasingly seen not as a replacement for developers but as a way to allow them to focus on more creative and strategic work. The transition from a senior individual contributor to an engineering manager requires a significant mindset shift, focusing on people management over technical execution. Aspiring managers are advised to voluntarily take on leadership tasks like mentoring and to clearly communicate their career goals to their current managers. Building strong relationships, developing communication skills, and gaining project management experience are key steps in this career path change. A strong focus on Developer Experience (DX) for internal tools is becoming as crucial as User Experience (UX) for external products. Good DX streamlines workflows, reduces friction for engineers, and can significantly boost a team's productivity and innovation. This involves providing well-documented, easy-to-use APIs and platforms that allow developers to self-serve and focus on building, rather than navigating complex internal systems.
