Ok kadbid, I am intrigued. what's the story? Why didn't you make the transition to other languages? Why didn't you make the transition into management? I'm not questioning your decisions, just curious.
C just happens to be the right choice for most of my projects today (I half seriously proposed FORTH for one before my cow-orkers threatened me with a dunking).
Let's make a distinction between Management as an HR function (writing reviews, dealing with org issues, fighting for equipment and office supplies) and Senior Geek Nirvana (design work, heavy lifting in code and debugging / shipping a product). I tried Management for a while, and it stunk.
Right now I'm in a great position as a senior technical guy (I hesitate to say "Architect" because most of the people I know with that title are self-appointed blowhards) who gets to decide how to do stuff. I lean on managers ("we need some chairs, and an oscilloscope") and project management (for setting up meetings, tracking bugs, etc.), and I get to write a ton of docs and code. It's terrific fun.
I'm living proof that you can be writing in C and not be a sour, dried-up dinosaur in the back corner of a lab somewhere.
