AI Found a Hidden Firmware Bug That Engineers Missed for Years

AI can spot hidden firmware issues buried in years of legacy code. Craig Wenger explains how AI helps embedded engineers catch bugs humans often miss.

You updated the LED control pin. Clean change. Looks right. But three years ago, another engineer referenced that same GPIO pin under a completely different variable name — and that code still runs. AI catches it. You might not.

Craig Wenger on why AI doesn't just speed up embedded development — it catches the things that slip through in legacy, multi-engineer codebases.
The bugs that ship aren't always the ones you wrote. Sometimes they were already there.
