I thought the article would be about replacing CTOs with AIs, based on the title.

Coding yourself out of a job?

cperciva made a similar comment about the title of "#define CTO": https://news.ycombinator.com/item?id=8518420.

Perhaps "#define CTO OpenAI" is an indication that being CTO is really operating as part of a team :).

Author should fix that bug, by changing it to #define OpenAI_CTO
