atrophied how? You can't write a for loop anymore? Nothing fundamental has changed in programming in the last 10 years.
There are so many languages and frameworks and design patterns and whatnot that it'd be surprising if you WEREN'T constantly running into stuff you haven't used before. Don't underestimate your abilities to pick up new stuff.
I just saw this post so I'm commenting very late... I feel that I'm better than ever at software development, and I've certainly come a long way. The problem is that I thought I'd be much further along than I am now(fwiw, I have about 6 years of working experience, and have been programming since high school). Maybe I feel like I'm behind as a result of so many new technologies that have crept up, but I still feel that a lot of the time at work is spent outside of software development on other things.
