The intersection of AI agents and developer tools is creating new paradigms for building software and communication platforms. In a recent a16z podcast, Resend CEO Zeno Rocha explores how generative AI is transforming email experiences, introducing the concept of “agent experience” as a natural evolution of developer experience, and how technologies like Multi-Agent Collaboration Protocol (MCP) are reshaping programming fundamentals.
The big picture: Developer experience expert Zeno Rocha reveals how his focus has shifted to designing for “agent experience” – creating interfaces and APIs optimized for AI agents that both build and operate within modern software products.
Email’s AI transformation: Email, despite being a decades-old technology, is becoming a fresh frontier for innovation as AI agents learn to send, parse, and optimize communications.
- Email remains one of the most ubiquitous tools for both developers and everyday users, making it a high-impact area for AI-driven transformation.
- Resend is reimagining email infrastructure for a future where autonomous agents handle significant portions of communication workflows.
Agent-friendly architecture: Creating effective APIs for AI agents requires fundamentally different design approaches than traditional human-centered interfaces.
- As AI increasingly participates in software development and usage, the boundary between creator and user is blurring, creating new requirements for tool design.
- Rocha discusses how developers can build systems that remain accessible to humans while optimizing for agent interaction.
MCP’s emerging impact: The Multi-Agent Collaboration Protocol (MCP) represents a significant advancement in how AI systems can work together, collapsing traditional creative workflows.
- The protocol enables more seamless collaboration between multiple AI systems, potentially revolutionizing how software gets built.
- This technology is creating unprecedented efficiency gains for both professional developers and prosumer creators.
Beyond the code: Rocha shares insights about his popular Dracula coding theme and his approach to side projects.
- The discussion reveals how personal creative outlets often lead to unexpected professional opportunities in the developer space.
- Rocha’s experiences illustrate how seemingly niche developer tools can achieve widespread adoption when they solve genuine pain points.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
