@Chumly,
What made you choose to be an electrician?
I think it was trying to get at the sense of the vastly different future that awaits us. Even though the changes aren't really sinister, we as humans by nature find change scary, especially when it happens so fast.
"What if?" is certainly a very engaging question, given the enormous number extrapolations and answers possible.
Personally I don't think by job would have to be "fun" as such... for it to be an intellectual challenge would be enough for me. I do enjoy creation - I suppose computer science could be considered a combination of science and art...
