Jag tror att detta är Nostalginauts av S.N. Dyer, publicerad i Asimovs mars 1997-utgåva och publicerad i Årets bästa SF 3, redigerad av David G. Hartwell (1998). Det finns en gratis ljudversion här :
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.
Och slutet:
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.
Det var också en av mina faves och både den och titeln har fastnat i mitt sinne.
