Brent Simmons follows up on that Dave Winer post with some future-friendly thoughts:
If I had to choose one or the other — if I had some crazy power but I had to wipe out either native apps or web apps — I’d wipe out native apps. (While somehow excluding browsers, text editors, outliners, web servers, and all those apps we need to make web apps.)
That’s not the case, though. Nothing has to get wiped out.
