Former OpenAI employee Kasra Kyanzadeh said that AI coding made him "miss people." Kasra Kyanzadeh Kasra Kyanzadeh worked at OpenAI for two months.

He said he worried that AI coding had "gone too far." He told Business Insider that AI agents let a single software engineer own a project.

That reality made him lonely.

"You don't get that same feeling of: We accomplished this thing together," he said.

Kasra Kyanzadeh missed working with people.

"I was like: Where are there smart people?" the 33-year-old engineer told Business Insider.

"At OpenAI, there are smart people." So, Kyanzadeh joined the team building the Codex desktop app in June.

By mid-August, he said he was feeling tired and drained.

He left to pursue filmmaking.

It wasn't OpenAI that was the problem, he said.

It was coding with AI agents.

Kyanzadeh is one of many engineers who have expressed fatigue with AI coding tools.

As AI transforms the job of a software engineer, some developers aren't happy with their new roles.

He had enough money to support a career change.
