I have no idea what job I would be doing if there were no computers. Since I got my first computer when I was 13 I've been pretty sure that I was going to be doing something with computers.
Maybe I would have become a vet, or something else that has to do with animals. I've always been fascinated by nature and all kinds of animals.
If I would have so much money that I wouldn't have to go to work every day, I would be traveling the world and making photos. (That's what my parents are doing since my dad has retired a few years ago - right now they are in South Africa and Namibia).
I would love to say an astronomer etc, but to be honest, I probably would have ended up in the Army, at behind a desk in the local bank or something daft like that!
The thing about growing up in India (at least back in early 90s) was that you had only a few options that were considered safe, or else you can continue studying till you are into your forties, accumulate a very long list of degrees to your name, and hope (in vein) of making a living from teaching!
