A different perspective.
When eggie was a young man, commercial HVAC systems were run by pneumatic controls or electro-mechanical. One good serviceman could work on all of it and determine if it was a mechanical breakdown or controls issue. Really good ones could fix both.
Fast forward, we now have every piece of equipment with onboard microprocessors. There is also a computer or multiple computers interconnected. Now we need a service mechanic, an automation guy, and a programmer/integrator to make all of this stuff work correctly.
Smart people adapt and learn new skills. Dumb ones don't and get left behind.
