I went to college in the late 90s. Didn't even own a computer until I was a freshman (used my loan money to buy one). Math and science had always been my subjects, so I started college pre-med. But, this new computer I just bought kept sucking me in. I'd stay up all night reading how to make it faster, learn all the tricks, and finally make it do what I wanted through programming. Next semester I took a programming class just to see how it went, then dropped everything, and switched majors. I got a part time job writing custom software for local companies as a sophomore/junior (late 90s dotcom was just ramping), and I guess it has all worked out ok.
