"Ethereum will have Visa scale transaction capacity in two years" is the headline of the article. However, that's not what Vitalik actually said. He did say "It will take a couple of years for the Blockchain to replace Visa."
Edit: He indicates that Ethereum developers have not settled on a scaling strategy yet .
My main reason for the quote is to point out that BitShares has already achieved for several years what other leaders can only dream of.
“Bitcoin is currently processing a bit less than three transactions per second and if it goes close to four, it is already at peak capacity. Ethereum has been doing five per second and if it goes above six, then it is also at peak capacity. On the other hand, Uber on average does 12 rides per second, PayPal several hundred, Visa several thousand, major stock exchanges tens of thousands, and in IoT, you’re talking hundreds of thousands per second.” -- Vitalik Buterin
