I find it interesting that symmetric ciphers like 256 bit AES are probably quantum resistant[0], while all currently used public key systems can be easily broken with quantum computers (because they're based on integer factorization and discrete logarithms). So any traffic recorded today[1] that is using Diffie-Hellman key exchange will be easily broken in the not so far future. This has made me appreciate pre-shared key systems again.
