To me the grunt work is getting data and for supervised, getting labelled data. Algorithm implementation and design is fairly straightforward and lots of fun. Of course, getting really good results in a domain is hard work - but again it's the fun bit. Then there are the domains and problems that can't be treated with off the shelf algorithms... well good luck!
