My wife asked me why I didn't throw out my old computer that I started coding my hobby project on years ago (a new kind of data management system). The computer is hopelessly outdated (a core2 duo) so I never use it anymore and the thrift store won't even take stuff like that as a donation.

I explained to her that it could be very valuable someday or used as a museum piece once my system is widely adopted and changes the world. I don't think she bought that argument.
