I should have said "recent past". I am not familiar with steampunk. I read Wikipedia article, but that's it.
But what about the present day? The technology that we might think of today as thing of the future might just be developed in some obscure lab today, or 5-15 years ago. Wouldn't it be fun to speculate in that direction?
There are quasi-modern-day sci-fi stories like the TV show Eureka or Fringe.
Going backwards just a little in time... Dieselpunk is often set between the two world wars. I loved the style of The Rocketeer, Skycaptain and The World of Tomorrow along with other post-aviation, pre WWII sci-fi/fantasies (even if the non-stylistic aspects of Skycaptain were deeply disappointing).
