I'd be inclined to say the gamer->modder->hacker path is generally less accessible in the mainstream today than it was 10 or 15 years ago. The above comment made me realize that's effectively the path I followed too, but can today's AAA titles be tinkered with the way Halo PC, Counter Strike, etc could be so thoroughly modified after a few hours poking through forums? I can remember the first time I used the (fan made) halo editing kit to play as an alien on the Silent Cartographer as a crystallizing moment for me to go from a computer
user to a computer
creator.I'd say Bethesda games are likely the exception - though from what I remember, trying to mod Fallout 3 mostly previewed to me how frustrating development can be :p
Edit: For what it's worth, I attended the Syracuse University ischool for my bs/ms and while that's also not a computer science program, my classes were usually at least equally proportioned between men and women. So that's at least a personal anecdote that the runway for women entering tech may be improving.
