## AI overview

The article argues that LLMs and agentic workflows are making software development less deterministic. It proposes managing uncertainty through verification, failure recovery, feedback loops, and processes that preserve both software quality and development velocity.

## Source excerpt

Software engineering has entered a probabilistic era. As LLMs replace deterministic workflows with uncertainty, the challenge is no longer eliminating variability; it's building systems that deliver both high quality and high development velocity despite it.
