## Authors

Michele Catasta

## Ton

**Profile**: VP of AI at Replit, visionary and entrepreneurial perspective, innovative register, energetic presentation for a technical and business audience

**Style**: Dynamic presentation blending strategic vision with technical demonstrations. Enthusiastic and provocative tone, using bold comparisons about the evolution of software development. Authority stems from direct experience transforming an IDE into an autonomous platform. Target audience: developers, entrepreneurs, and technical leaders interested in the future of development.

## Pense-betes

- **Two types of autonomy**: Supervised (Tesla FSD - with license) vs Full (Waymo - without license)
- **Third dimension of the Swyx plot**: Autonomy for non-technical users
- **Painted Doors Problem**: 30% of generated features are broken on the first attempt
- **Autonomous Testing**: Solution to the feedback bottleneck for non-technical users
- **Verification spectrum**: LSP → Execution → Unit tests → API testing → Browser testing
- **Computer Use vs Browser Use**: Trade-off between fidelity and performance/cost
- **3 agent generations**: React-based → Native tool calling → Autonomous (>1h runtime)
- **Scoped control**: The agent makes all technical decisions, the user retains product control

## RésuméDe400mots

Michele Catasta, VP of AI at Replit, presents a bold vision of full autonomy for coding agents aimed at non-technical users. He introduces a third dimension to Swyx's well-known chart: beyond latency and autonomy, accessibility to non-developers must be considered.

Catasta distinguishes two types of autonomy using an automotive analogy. **Supervised** autonomy (Tesla FSD) requires a "driver's license" - the user must be technically competent to intervene. **Full** autonomy (Waymo), which Replit targets, allows users to "sit in the back seat" with no technical skill required. This vision aims to democratize software creation for all knowledge workers.

The **"Painted Doors Problem"** is a major challenge: 30% of features generated by agents are defective on the first attempt, creating non-functional dummy interfaces. Non-technical users can neither diagnose the issue nor provide the technical feedback needed. Replit's solution: **autonomous testing**, which lets agents verify their own work without human intervention.

The technical evolution unfolds across three generations of agents. The first, React-based, offered basic autonomy. The second integrated native tool calling. The third generation, recently launched (B3), breaks the one-hour autonomy barrier while remaining coherent on long-running tasks. This autonomy remains **scoped**: the agent makes all technical decisions while the user retains control over the final product.

The code verification spectrum has evolved from static analysis (LSP) toward more sophisticated approaches: execution, unit tests, API tests, up to browser testing. Replit implements a hybrid approach combining Computer Use (direct but costly interaction) and Browser Use (DOM manipulation, more efficient) to automatically test generated web applications.

The presentation reveals that autonomy does not necessarily mean slowness. An agent can be fast AND autonomous if the task scope is narrow. Users retain control over what they build, not how it is built. This separation of concerns allows knowledge workers to create software without technical expertise.

Catasta concludes that this transformation represents a fundamental shift: moving from coding assistance to the full delegation of technical implementation, opening software creation to millions of new potential creators.
