I'd like to preface my answer by saying that I believe I have yet to create something truly "original." Every edit I make, fader I move, or plug-in I tweak is still an offering of thanks for the knowledge that has been passed on to me by teachers I know and an homage to those I have never met, but have certainly heard.
Maybe I haven't been doing this long enough (only 11 years), but I think I actively fight finding my voice.
After working with me on a number of projects a co-worker of mine said, "I can always tell you sound designed a show, it's always.." and then went on to describe what he thought was my style. The very next project I deliberately abandoned every method and characteristic that he described and did everything I could to start with new ears. The same co-worker came to me with a smile after the playthrough, "was it something I said?"
I think that my biggest fear in finding my voice/style/signature is stagnation. To me, stagnation in creativity is death. I have since begun to re-incorporate aspects from that original "style" but it is a conscious effort, used at appropriate moments, rather than an unnoticed flow.
That being said, I do find merit in the argument that by having a recognized style you'll have a tendency to be highly marketable to the clientele that your style fits well with. But styles can be trendy, and I hope to do this for a lot longer than a trend's cycle.
This may just be my relative inexperience and ignorance, (after all, I do keep a busy calendar but am hardly in demand) but I'd rather have a reputation for being a dedicated worker, a creative thinker, or a talented professional that can get the work done regardless of style. That's something that I actively work on every day that I still haven't gotten on top of.
As far as technology goes, it's all wheels, hammers, and levers. That is to say, technology is just a tool. How I think about the tool and it's relation to the problem is usually what determines my success or failure in using it.
