The Human Cost of 10x: How AI Is Physically Breaking Senior Engineers

The Human Cost of 10x: How AI Is Physically Breaking Senior Engineers Your brain processes 10 bits per second. AI just increased your review queue by 98%. The math doesn’t work.

In the past year, the volume of information passing through my brain on any given Tuesday has become what used to take a week. Code review is the worst of it, but the real killer is the context switches. AI-generated PRs, client architecture decisions, three Slack threads about deployment issues, a candidate’s CV that needs review, an air defense alarm outside the window, then back to reviewing code that a machine wrote in seconds and I need hours to validate. Each of these demands a different mental model. Each one burns working memory. By 4 PM I’m making decisions I wouldn’t trust from a junior. By 7 PM my brain is physically empty. The industry calls this “10x productivity.” I call it what it is: a system that generates output at machine speed and forces humans to process it at biological speed. Workload Creep In February 2026, UC Berkeley researchers published findings from eight months embedded inside a 200-person tech company. Over 40 in-depth interviews. Thei…
