I assume it's not a reference to responsive ("self-resizing") HTML, but rather things like user input lag (a common problem in apps.) Better to have a zero-lag async calculation than a nominally faster but UI-blocking synchronous calculation or request.

I think it's actually meant to encourage putting up things like spinners, page transitions, etc. Make the user feel that something is happening, and they won't feel slowed down.

  But that doesn't mean it is better than fast. I would say "if not fast, be responsive"

    I think the message is this: fast is an impossible standard to meet since there will always be inconsistent user experiences, so aim to be responsive before being fast.
