I'm not the guy you replied to, but come on. Install some big software like MATLAB or MS Office, oh no there goes several GB for each one. Set up a few VMs, oops there goes tens more GBs. Install some modern video games, multiple GB each one. And that's without even getting to the obvious culprits of pictures, music, and video.
64 GB would only work for a computer used almost exclusively for doing things on remote systems (browsing internet, working on remote servers, storing things on external HDs, etc).
