A Brain is Alive in a Computer
Summary
This intelligence brief critiques an essay by AI startup entrepreneur Matt Schumer, which claims AI progress is rapidly accelerating, particularly in code generation. The analysis, provided by Cal Newport, refutes Schumer's assertion that AI models experienced exponential growth in 2025, stating that general capability improvements slowed post-GPT-4, leading companies to focus on narrow, post-training tasks. Newport highlights that while coding agents like GPT-53 Codex and Opus 4.6 show incremental progress in specific programming tasks, they do not enable programmers to fully automate app development by simply describing requirements and returning hours later. He also dismisses the idea that AI writing code for itself will lead to recursive self-improvement and a general AI takeover, labeling it "gradeA nonsense" and a misinterpretation of current AI capabilities.
Key takeaway
For CTOs and VPs of Engineering evaluating AI integration, recognize that current AI tools, while useful for specific programming tasks, do not yet support full automation of app development. Your teams should plan for heavily supervised AI use, focusing on clear specifications and extensive testing for AI-generated code, rather than expecting a "set it and forget it" workflow. Avoid alarmist narratives about exponential AI growth or self-improving agents, as these claims are not supported by current technological realities.
Key insights
Current AI progress is incremental and specialized, not a general exponential acceleration or self-improving loop.
Principles
- General AI capability growth has plateaued.
- AI progress is often task-specific and incremental.
- AI models do not self-improve or invent new intelligence models.
Method
AI companies shifted from general pre-training scaling to post-training and fine-tuning for specific applications, such as coding agents, to achieve incremental improvements and find viable markets.
In practice
- Use AI for tedious, structured coding tasks.
- Extensively test AI-generated code for accuracy.
- Focus AI applications on narrow, well-defined problems.
