A 64 character password is so incredibly strong (especially if it's
random) that it doesn't matter much about how fast computer
technology advances, it still wont be feasible to break it. This is
especially true due to the Landauer Limit, which basically means that
the energy requirements for the computation would be too large to be
feasible. You must take energy requirements into account and there
isn't enough energy on earth to do it.

Quantum computers are the most effective against asymmetric (public
key) crypto and are less effective against symmetric ciphers like AES
or Twofish. The best a QC can do against something like AES is cut
the keylength in half. Thus, AES-256 will be as hard to break for a
QC as AES-128 is for classical computers.
