A decades-old rule of business has broken: more employees no longer means more output. At Block, the correlation between headcount and productivity shattered in late 2025, leading to a restructuring that cut over 40% of staff, primarily from software development.
On The a16z Show, Block executive Owen Jennings explained the shift is technological, not just financial. The company now operates with squads of one to six people instead of large, siloed teams. Human engineers no longer write code by hand; they manage fleets of autonomous agents through internal tools like Builder Bot, which autonomously merges code and ships features. Designers and product managers now ship their own code directly to production, compressing development cycles from months to weeks.
Owen Jennings, The a16z Show:
- There's been this correlation between the number of folks at a company and the output from the company for decades and decades.
- I think that basically broke.
This agentic shift is remaking the entire AI industry. The chatbot era is over, replaced by what Nathaniel Whittemore on The AI Daily Brief calls “AI's second moment.” The economic stakes are now industrial, with hyperscalers deploying $650 billion in capital expenditure this year. Anthropic has become the default enterprise choice, capturing 70% of first-time buyers by making its core tools, like Claude Code, extensible for building entire workflows.
The result is a “SaaSpocalypse.” Investors are fleeing public software stocks - the S&P 500 Software Index fell 20% - fearing that AI agents automating entire departments will collapse the traditional per-seat SaaS revenue model. The logical endpoint, as demonstrated by the agent-run company Pulsia generating $6 million in revenue with a single founder, is the zero-employee company.
Yet most organizations are unprepared for this transition. According to Whittemore's AI Maturity Maps, companies are misallocating resources, directing 93% of AI spending to infrastructure and only 7% to training people. This creates a capability overhang where the technology's potential far outpaces an organization's ability to use it. Sales teams claim 88% adoption, but less than a quarter have AI integrated into actual revenue workflows; most are just drafting emails in a separate ChatGPT tab.
Success requires a fundamental change in how humans work with machines. As Anthropic's Jack Clark explained on The Ezra Klein Show, agents are not intuitive colleagues but literal-minded genies. To get professional results, humans must become architects, writing exhaustive specification documents rather than vague paragraphs of intent. The new senior engineer is a context-manager, not a builder.
The disruption is just beginning. The race is between companies like Block that are restructuring around agents and the vast majority that are investing in compute without investing in their people.
Nathaniel Whittemore, The AI Daily Brief:
- The irony is that one could argue that the single largest barrier to converting AI adoption into AI value is on the human side, and it's the thing organizations are spending the least on.
