The only reason that ASICs are winning is that ASIC manufactures are bribing developers to do nothing about ASICs taking over an algorithm. It would be very easy for a coin like Zcash to tweak Equihash and prevent all of the Z9s from mining. (Monero showed how simple and effective it is.) Contrary to Vorick's claims, ASICs cannot easily get around such a change -- if they were able to, then they wouldn't be much more efficient than current GPUs.
The author of the blog sells ASICs, so it's in his best interest to make GPU miners think there is no hope. He's also a very sleazy person. He accepted crowd funding for five batches of Siacoin ASICs almost a year ago and has yet to deliver a single product. So given his behavior, I can't trust anything Vorick says. In fact, I'm inclined to believe he's a compulsive liar who will say anything to get money.
In the article, he stated substantiated facts. You posted a bunch of speculation, guess and conjecture glazed over with personal opinion and unwarranted optimism. In short....he's right and you're wrong.
