In the era when development became free, we now put a price on 'taste'

• Building is free: Starting a feature from a blank slate is no longer difficult.
• The value of curation: Among the outputs independently built by 90 teams, deciding what to choose and combine, and judging the product’s goals and direction, has made 'taste' a core asset.
• Choosing the right medium: The answer is not always to make a prototype. When you need to clarify direction, a 'document (PRD)' is useful; when you need to validate interactions, a 'prototype' is needed. Choosing the right medium is also part of taste.

② Changes in the design process and roles

• Reinterpreting the design process: The traditional design process that upheld procedure itself is over, but understanding "where you are in the process" has become even more important.
• Roles do not disappear: Completely eliminating roles and turning everyone into 'builders' is a risky choice that throws away accumulated professional best practices.
• Breaking down boundaries: Silos between functions are becoming blurred, but collaboration will happen in a 'zone defense' style, where teams cover broad areas while having only the 'average' level of expertise in each field.

③ OpenAI’s product strategy and future

• Model-timed release: Rather than building a long roadmap, they create feature prototypes in advance and launch them when the 'model’s intelligence catches up'.
• Integration of Codex and ChatGPT: Codex is evolving beyond a simple developer tool into a 'super app' home base for knowledge workers, directly operating and connecting with other professional apps like Excel and Premiere.

###3. Key takeaway

"In an era when implementation speed has hit its limit, what matters is not the ability to write code, but 'taste' that separates signal from noise and the direction to decide what to ship, and when."
