I think you're right, but in a different way than I understand that you mean. Whatever project I'm on I try my best to take on the hardest tasks. This allows me to code against things that are actually a challenge. Large refactorings, risky features, hard we-arn't-sure-if-this-is-possible tasks. This makes 40% of what I do hard. But it isn't because I'm writing software for ICMBs or satellites. I'm the dude that takes on the tough stuff and makes it work, and I think more developers would do themselves a favour if they did the same thing. Maybe you don't need to quit your job in order to change the ratio. If there is work at your present place that seems hard then volunteer for it. It will make you a better software developer.
