> multiple cursors really are better than macros 99.999% of the time (since they give direct visual feedback)
I don't know what he means, vim macros also give direct visual feedback while writing them. You just edit as normal while recording, and replay those edits later. I think it is technically possible to write a macro without seeing the live effect on the text as you write it, but I've never done that.
I looked up multiple cursors out of interest, I guess the advantage is that it's one interface that is easy to explain. I would use multiple vim commands to replace it in practice.
I'll agree that multiple cursors are maybe better than macros for most of the things that someone would use multiple cursors for, but usually I wouldn't use macro's.
But I think most of the things I do with macro's cannot be done with multiple cursors.
I would be very interested in being proven wrong, if someone has some examples of "this is where multiple cursors are great, and vim doesn't have a good alternative".
