As AI drives the cost of building software toward zero, developers must find what remains defensible.

“if the cost of building software is approaching zero does that means that the value of building software is also approaching zero”

In a Build talk, AI systems builder Chip argues that AI is rapidly driving the cost of generating code toward zero, enabling things like thousands of AB-test variations, and asks whether that also drives the value of software toward zero. The talk frames the open question of what skills and software remain defensible when writing and coding are the tasks AI most easily automates, but this excerpt is mostly setup and anecdote without a concrete answer or announcement.
