Yep, this is the way. It survives human memory and doesn't depend on software. If you keep it in a dark environment that's not super humid the ink should last

Yep, this is the way. It survives human memory and doesn't depend on software. If you keep it in a dark environment that's not super humid the ink should last a really long time. Even in non-optimal conditions (NY summers with high humidity, etc.) I've had regular pen ink last for decades with no signs of fading away.
