I think you are making a false dichotomy here. It is perfectly possible for the article to be right, and there is still a future with general artificial intelligence and a singularity. If you believe the singularity is inevitable then you should read the article as saying that we are woefully misjudging where the asymptote is -- yes current progress looks impressive, but there are some really big steps that we are currently ignoring, and real human level AI is a century or two out, not a decade or two out. That's perfectly possible, and most philosophers who work in consciousness and philosophy of mind (as well as a very large portion of the machine learning community) will tell you that there is still some big hurdles that we don't even have the faintest idea how to cross (the whitehouse report on AI described it as a "chasm").
