Paper will last.

If you wanted to ensure it lasted for 150 years – you’d choose paper:

As amazing as our current electronic technologies are – despite their strengths – are terribly, terribly ephemeral. The code that worked yesterday isn’t support today. The processors of – five years ago, ten years ago – are brought to their knees by the computational complexity and presumed processor capabilities of today’s software. The runtime environments required by the digital creations I manifested as a University student not only do not exist – computers of today don’t even recognize the file types.

This is why my journal is on paper, my todo lists is on paper and that my planner is on paper. I know they will be readable in the future(if you understand my hand writing).
