REAL STORY A split screen. Left: a countdown timer showing '30:00' in red. Right: a terminal with Claude Code running -- it has found a bug in a file, displayed the problematic line, and proposed a fix. The timer on the right shows '4:00 elapsed.' 26 minutes to spare. Intense but clean.

30 minutes to fix a production bug. The on-call engineer opens a terminal and types 'claude'.

Claude Code reads the entire codebase. It finds the bug in 90 seconds -- a race condition in the payment processing module. It explains what's wrong, writes the fix, and runs the test suite. Four minutes total.
