Introduction

This interview with Patrick Collison, co-founder and CEO of Stripe, explores his perspectives on programming languages, the impact of AI on software development, and key engineering decisions made at Stripe. The conversation covers a wide range of topics, from Collison's early programming experiences to his views on the future of software development and the economy.

Key Takeaways

• Smalltalk's Advantages: Collison discusses his first startup, built using Smalltalk, praising its powerful development environment and debugging capabilities. He contrasts this with the limitations of other languages like Ruby.
• AI's Role in Software Development: Collison anticipates AI's increasing role in assisting with coding, refactoring, and improving code quality. He envisions a future where AI acts as a collaborative partner, handling background tasks and providing suggestions.
• Stripe's Engineering Choices: Collison details significant engineering choices made at Stripe, including the early adoption of MongoDB and Ruby, and the subsequent rewriting of core services in Java to address performance needs and scale.
• API Design's Importance: He emphasizes the long-term impact of well-designed APIs and data models, illustrating this with the example of the iOS ecosystem's success compared to Android. Stripe's recent V2 API is highlighted as a result of this focus.
• The Future of Programming: Collison suggests a shift towards higher-level, less formal programming languages facilitated by AI, potentially involving more direct manipulation of the user interface. He expresses concern about the lack of experimentation with programming paradigms in recent years.
• AI's Economic Impact: While acknowledging the difficulty of predicting AI's impact, Collison discusses various perspectives on its effect on economic productivity and GDP growth, highlighting ongoing debates and the need for potentially new economic metrics.
• Programming Human Biology: He expresses excitement about the potential of AI and new biological technologies to revolutionize understanding and treating complex diseases.

Stripe's decision to rewrite certain services in Java stemmed from the limitations of Ruby in handling high throughput and demanding performance needs as the company scaled. Specifically, the limitations mentioned were fighting against the allocator and inefficiencies in aspects like Ruby strings. While optimizing Ruby (including rewriting hot paths in C) could yield some speed improvements, it wasn't sufficient to meet the demands. The rewrite to Java addressed these performance bottlenecks, leading to significant improvements in reliability and speed. One metric cited was Stripe’s 99.99986% API availability in the previous year—only 44 seconds of downtime.
