It's ugly, though. "They" is a plural. I just used it in my last post, but I didn't like doing it; now it is gender-sensitive, but ungrammatical.

I also used the phrase "a new man", because "a new person" doesn't have the history of use that invokes the noble/creepy feelings that I wanted to communicate. I couldn't think of any gender-neutral way around it.

If we took a vote, I'd vote for "it". It also has a nice, dehumanizing ring to it, which would probably be good, given our anthropic tendencies.
