I cannot possibly take the guy-who-wrote-"are we human, or are we dancer"'s complaints seriously.
But it is astonishing that when thinking of bands that will be remembered forever, Beatles, Stones, Zeppelin, even U2, Radiohead, Pearl Jam, Pumpkins.....what band that has come out in the last even 10 years will ever gain that status?
Bands that already have a shot at it:
Coldplay | Kings of Leon | The Killers | The White Stripes
Bands that may yet have a shot at it:
My Morning Jacket | The Arcade Fire | LCD Soundsystem | Death Cab for Cutie | Muse
I also think Silversun Pickups, The Raconteurs, Yeah Yeah Yeahs and some others have potential to go down that road, but it is too early to tell.
All of them are bands with great live shows and big followings that don't show any sign of letting up at the present. I'm not necessarily saying they're as good or as relevant or what have you - but they're on the rise, and have big catalogs (excepting LCD and Arcade Fire) that would seem to indicate that they have some staying power and ability to keep churning out good (or, marketable) material.
And, like it or not, there are plenty of budding stars in non-rock realms that are going to be stars as big as the folks you mentioned (see: Taylor Swift, et al)
UPDATE: Oh, and Daft Punk's last tour ensured they'll be remembered forever as having one of the best live shows of all time.
