Since reading the fifth HHGTTG book (where Arthur Dent becomes The Sandwich Maker), I genuinely worry what use I would be to a society that doesn't have the internet, computers, technology, science-fiction culture, and all the other stuff that I've grown up with, know, love, and completely take for granted. (Only occasionally, mind you— but genuinely.)

Having a degree level education in Chemistry is all well and good, so long as you have a fully stocked laboratory and would like me to run some experiments, but I'm not so sure what I'd be able to do with it if I was stuck in a thousand year old culture. Other than maybe baffle them with stories about atomic science, quantum and relativity which I'm not entirely sure I understand myself.

Luckily, when I do find myself with a time machine, I've now got the first thing I'll want to put in it.

(Now I just need to figure out how I'd get to Greenland...)
