This is a remarkably clueless article. It's clearly written by someone not familiar with the demands of embedded systems. Also, Pis have a not-so-stellar track record as far as reliability, which is why I wouldn't want to use them in safety-critical systems. I suspect systems using them will have a hard time passing official reviews (which have been accelerated, but very much still exist).
