I'm already seeing people pile in here to call Stefan Thomas a business scammer and "a competitor calling his competition a bust" and whatever, so it's worth mentioning here that Stefan pioneered using Bitcoin with Javascript, and the most popular wallets in the world still use what he helped create today: http://bitcoinjs.org

Please have respect for the idea that his opinions on Blockchains aren't just biased in connection with his work and possessing of no technocratic merit. If you don't at least give him that, he will have received neither money nor respect for his hard work that definitely improved the Bitcoin space (because he sure wasn't getting paid to work on BitcoinJS).
