My old mentor could smell a bad capacitor. Now we just swap boards.

Avionics was hands on with visible wires and components. Faults had physical signs like heat or smell. Now it's all digital systems and software. Diagnostic tools give data but not insight. Where's the troubleshooting skill? I miss the tangible fixes. Are we losing the technician's craft? It confuses me how reliant we've become.

Question whether swapping boards is really a loss of skill. Maybe the craft just evolved into reading data faster than any human could smell a problem.

Totally disagree. Swapping boards turns troubleshooting into a simple parts lottery. The real skill was in tracing a faulty capacitor or transistor with a meter and a schematic. Now it's just reading codes and guessing which expensive module to throw at the problem first. That's not evolution, it's just replacing deep knowledge with a faster guess.

Hear you, @abbyharris, but it's a different skill set.

But is it really that big of a deal? Like derekhunt said, the craft changed. Now you need to know how to read a live data stream and understand systems talking to each other. That's still a real skill, just a different one.
