Like, would Hephaestus be the god of magnetos, distributors and capacitor discharge ignition systems? Or does that count as lightning and thus be Zeus’ problem? Is Oden the god of whiskey because it necessarily must be made in oak barrels, or being booze would that fall under Dionysus? Is Mercury the god of SMS?
What you’re thinking about is one of the main plot points of the book fiction book “American Gods”. The premise being that gods cease to exist without followers. So the old gods need to attach themselves to new things/subjects to scoop up those worshipers and continue to exist.
An example Vulcan became the god of firearms and began manufacturing ammunition where each bullet fired was a “prayer” to him, empowering him.
