As a programmer, I'll likely be making off-by-one mistakes until the day after I die
Addendum: As a test engineer, I'm hoping to die on a leap day, during a daylight savings change, or at least after the unix epoch expires. Ideally some combination of the three, perhaps with a Lazarus syndrome or two thrown in before finally circle-strafing towards the light.
@dotjayne now with AI you can make a program that will create errors for you for years after you die
