Could you elaborate on what you mean by that? Is it the standard scope creep / premature generalization pattern, or something else?
Engineers are likely to solve problems that the customer doesn't care about. If you know engineers that say things like "the customer is an idiot" then you understand what I'm talking about. Even if the customer really is an idiot that is the person who needs to use the product.
I’m not sure you can generalize like this. Do the engineers have RSUs or financial incentives where they do better if the firm does better? I’d argue they’d care more then. Also, a lot of engineers intentionally chose to work in market segments they’re passionate about. I’ve been at the same company for over 13 years. I could likely make more elsewhere but I find the domain I work in quite rewarding and interesting.
They have a larger emotional incentive to work on cool things that they enjoy, as opposed to the relatively small change in company price if their individual product succeeds or fails.
