Depends on what they value. Old people love new technology when it solves their problems. Health is a big motivator. If you invent a gadget that cures arthritis, I guarantee you millions of "technophobes" will be among its early adopters.
My chain-smoking grandmother considers herself a luddite, but in a sense she's bleeding edge. If I had a nanobot pill from 30 years in the future and with it I could return her lungs, arteries, skin etc. to the condition they were in when she was 25 - I know from talking to her that should would be ecstatic with techno lust.
To win over a luddite, ask yourself what they most desire that they can't currently get. Sometimes the technology is already available. If so, demonstrate it solving some vexing problem they have, or think they have.
