Agree, as engineers we should be making the car easier to operate instead of making everyone a mechanic.
Focus on the simple iteration loop of "why is it so hard to understand things about our product?" maybe you cant fix it all today but climb that hill more instead of make your CEO spend some sleepless nights on a thing that you could probably build in 1/10th the time.
If you want to be a successful startup saas sw eng then engaging with the current and common business cases and being able to predict the standard cache of problems they're going to want solved turns you from "a guy" to "the guy".
Most engineers like being mechanics though.
