It's one thing to needlessly criticize a new business (start up), or an espoused goal (hyperloop) but a completely different situation when bringing in some run-of-the-mill skepticism. I think skepticism is healthy - it's one of those interesting emotional/intellectual mechanisms. In the most effective circumstances, skepticism seems to blend past experience + current facts + future hypothesis, all of which fit into the context of the referenced article.

Generally I don't bring much of any philosophy into the skepticism approach. Every once and a while though, it does play a role. I'm not really proud of it, but I'll publicly admit that I was so utterly repulsed by the Aurous concept that I did a little happy dance when market forces (i.e. the RIAA) took on Aurous, shut it down fast, and moved on from the dead carcass. Am I happier for its demise? Yep.
