If they can't appreciate my job, I will simply did into their so deep that by the end of the conversation, I have rough idea of what function does their job perform and where are the pain points for them.
I usually weave in some personal job-related stories for them to relate to my job a little bit better. Usually they are left stumped, because nobody ever digs and then gets them. Especially not an Aspie programmer.
It's also easy to find some of their efforts you appreciate and then compliment them on those.
I think it's better to state the field you're in rather than your job title. For example, if you work for a bank, say "finance".
Secondly, when i tell people that i am a technologist, it almost feels like one of those groupings of jobs like "doctor", "architect", "lawyer", etc. Sure, maybe that's more for my ego, but who cares. ;-)
