This makes me wonder what remnants we'll have left of the greats of this generation amidst tech juggernauts bound to fall and every URL expiring after only a few months. People forget passwords, the owners of accounts die, hard drives fail, but ephemera like letters are tangible things that can last longer if stored properly. I think in the future they'll just say "x was known to have an account on defunct service Instagram and his profile picture on his private Facebook account has him wearing sunglasses".
