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.
Better examples of the intersection of science and art might be found in the work of someone like Buckminster Fuller. The nature of science being what it is, the science probably has to come first, with the art emerging from it

Most of science fiction kinda disputes this though. A scientist has to have the imagination to construct the experiment.
As another commenter mentions, I do think it is productive to discuss the line with which something is no longer "rigorous" enough to be considered science. The caveat is that these discussions should be made by the lab doing the work, not by the Internet peanut gallery.
Media Lab's "research" resembles constructive science rather than deductive science (how does the world work?). We normally forgive science papers for doing engineering when they present something that is immediately useful to humanity (e.g. TensorFlow whitepaper). Artists (fashion designers, creatives, etc.) often make cool demos but fall short "revolutionary" products because the fabrication technology is not ready yet for their ideas. It still has a place, though, in science - if only to suggest unorthodox ways of approaching scientific inquiry.
At the very least, these works realize thought-provoking concepts a step farther than most of us are willing to commit to -- chatting about it on the Internet.
FWIW, my day job is doing science, if that lends my comment any credibility.
