The stereotypical person from the "hard science" communities will never totally buy into this kind of work being science. It's not exact, it's not rigorous. On the other hand, artists and designers more often inhabit this speculative, rapidly-prototyped, thought experiment-esque mode of creation and take it as a valid form of inquiry.
Personally, I love it. It's not hard science or hard engineering in the same way that someone in EECS or biology might treat those fields, but it's a wonderful way to root artistic exploration in current scientific technique.
Is that the right balance between the two? Is there a point along the spectrum where you need to stop calling yourself a scientist and start calling yourself an artist? I think that's an open question.
