Eu acredito que isso é The Nostalginauts por S.N. Dyer, publicado na edição de março de 1997 de Asimov e republicado em Year's Best SF 3, editado por David G. Hartwell (1998). Há uma versão em áudio gratuita aqui :
When time travelers first started showing up they were called phantoms. When scientists figured out what they were, the media called them time tourists, or nostalginauts. We stuck with phantom, pronounced phan-dumb, and finally just dumdums.
I mean, what a phenomenally stupid invention. Time travel that only takes you twenty-five years into the past, lasts half a minute, and you’re insubstantial too. It makes a quest for rubber beverage containers look intelligent.
E o final:
But I still had my patented sardonic grin, as my future self flashed up something white.
“Not pictures,” I moaned.
No. It was an index card. My handwriting didn’t seem to have improved either. I’d scrawled, “IT HASN’T BEEN DULL.”
I shrugged at me and disappeared.
It hasn’t been dull.
Cool. I can live with that.
Foi também um dos meus favoritos e tanto o título como o título ficaram na minha cabeça.
