The same people who 100 years ago might have thought "OMG, if I only could work in aeronautics, it would be sooo cool and exciting" now look at it as, meh, just another possible desk job."

Or, you could try to get a job working for one of the firms trying to commercialize space flight.

Or, if automobiles are your thing, you could try to get a job a Tesla motors...

Name the industry, and there is probably SOME area in which new, interesting work is happening.
