That's true. I feel the urge to use new shiny stuff pretty often, but have no choice but to use old robust solutions, because new ones are just mostly proofs of concepts. This is also extremely true about the whole web-dev thing (the good ol' one JavaScript framework a day).

I guess it just comes down to working ethics. Doctors are a good example. Among them there are people who just do a job, who aren't passionate about the whole saving lives. And those are people that work directly with patients and heal people. Now imagine how bad a situation is when a person doesn't work directly with people and responsibility seems little. Among developers, there are people who are genuinely concerned about quality of the code they produce, but they are a minority. There are far more of those, who came in the field just because that's the next big thing and where the money's at. They just spend their whole day ramming that badly written code in a badly written codebase because manager told them to get it done by the end of the day. They don't see the consequences of their actions.

I read something like "a bunch of developers are controlling data of millions of people" some time ago. It feels relevant. Quite a lot of developers don't realize the scale of impact their software can have on people.
