The article seems to conflate the praxis of science with the archival of it. Scientists do all of the above on gigantic clusters, not on an IPython/Mathematica notebook. The purpose of publishing papers, on the other hand, is adding to the archival of knowledge, and they can be easily rendered in a laptop with LaTeX.
And they are excellent at archival, by the way. You can see papers from the 19th century still being cited. On the other hand I have had issues running a Mathematica notebook from a few releases back -- and I seriously doubt one will be able to read any of my Mathematica notebooks 150 years from now. The same with the nifty web-based redesign of the Nature paper that is mentioned: I bet the original Nature article will be readable 150 years from now, whereas I doubt the web version will last 20.
