Are you 100% convinced that QR codes will be common enough in a 100 years for common people to figure it out?

I’m not.

Yes I am 100% convinced (barring apocalypse etc.)

Would you know what to do with a record? That's 150 year old technology. If not you know how to look up the information hopefully?

OTOH, would you know what to do with a wax cylinder (or even what it is?) or how about an 8-track cartridge or a reel-to-reel tape?

And, if you knew what to do with these things, would you be able to actually do it?
