Summary
Takuto Wada’s month-by-month account of his 2025 output — 53 talks, 12 training courses, six podcast recordings and the supervised translation of SQL Antipatterns 2nd edition — framed as a record of the year the way software is built changed. It tracks his own adoption of coding agents: Claude Code from March 2025, the incentive shift when it became available at a flat rate on the Claude Max plan in May, the talk “Thinking about software development in the age of AI” that became his most-read deck of the year, and his first spec-driven development training course in December. His closing claim is that 2025 was the year automated testing finally became ordinary, because AI agents cut both its learning cost and its implementation cost — at the price of heavy semantic diffusion in the terminology.
